THANK YOU - who knew ACRONIS was the mystery culprit? You did.

Glad I found you! I suddenly discovered I was unable to access my networked XP drives from my Vista system. Yep, TrueImage clones great (Kudos to them for that). Unfortunately it seems to really hose the registry and disallows network disc/file shares. Uninstalled on XP systems and all is well once again. Just for kicks I upped IRPStacksize to 20. That made for much faster access from Vista to the XP-drive it appears to me. But the fix for "Not Enough Server Storage" was uninstalling ACRONIS TRUE IMAGE. Thanks again - great, great, site.

I had never considered that True Image might be the culprit (even though the only new thing i installed today was True Image Doh!). I have Norton 360 and True Image 11. I had had problems with Norton 360 before and figured that was the cause. Should have know something was off when I disabled the firewall and it still didn't work. Curious thing though File Sharing worked after I uninstalled Norton 360 and still had True Image installed. It must be something to do with the combination of the two.

I was able to get File Sharing back by setting IRPStackSize to 16. The key was not in the registry, I had to add it.

My fix required a setting of 30. Don't know if this is because of my config. or not but here it is:

I'm running various virtual machines using Hyper-V

Host: Win Server 2008 R2 x64
Guest-1: XP Pro x64 - Acronis Home 2010 - IRPStackSize = 30
Guest-2: XP Pro x64 - Acronis Home 2010 - IRPStackSize = 30

Prior to applying this fix, with Acronis installed on either guest PC the networking stopped working between these 2 VM's. The interesting thing is that networking with other PC's to or from these 2 VM's on my domain worked OK. The issue was only between the 2 XP VM's. Incidentally, all PC's, VM or otherwise on my domain, have Acronis installed. The servers have the server version and the workstations all have 2010...

To confirm it was Acronis I uninstalled Acronis from the VM's and networking was restored. Reistalled Acronis on the VM's and the network stopped working but only between the 2 VM's.

Regardless, this fix worked when applied to both VM's!

THANK-YOU :)

Fix worked perfectly for XP server & Windows 7 client laptop. Had to create reg entry as it did not exist. Not sure of the root cause but I am running Acronis True Image 2010 & problem ocurred immediately after upgrade from 2009.

I almost never sign up to boards but just had to this time in order to say:

Many, many THANKS!!

it was my Acronis. Increased the IRP size and now everything is OK. Two days of misery. This website is awesome. thank you.

This issue bugged me for months, or maybe it was years. I used Seagate diskwizard for a couple of years, and from time to time my wireless XP laptop could not "see" the shared drives on my main (XP) machine. At this level I could stumble on.

But then I installed the trial version of Acronis Home 2010. I did not even run it. I was pretty well locked out of the machine it is on. Worst of all my OneNote would not synchronize.

I had no IRPStackSize key and made a new one. I have set the value to 26. All is serene.

This was my best tech forum experience.

Thanks for this fix, great to have my network access back. Problem started when I took a long overdue update for Acronis (not 2010).
My IRPStackSize was set to 11, I updated to 15 but no fix. Lacking patience I went to 20 and all is OK.
By the way a Microsoft article on this says to set it to decimal, which I did; but had to do this each time.
(Server is XP pro, client is Vista)
Thanks everyone for the posts!

Amazing. It worked. I was nervous changing the registry but I got it. Thanks to whoever was smart enough to figure this out.

Many thanks to you for providing this solution which has been occupying me for 2 days! I was happily sharing my files between two XP Pro, one XP Home and one Vista Home Premium systems until I upgraded Norton 360 from V2 to V3 and Acronis TI V11.0 to 2009 home. I used one XP Pro Desktop as my 'server' and suddenly I was no longer able to access this shared data. Having eliminated the obvious suspect (Norton firewall!) and reinstalled all my file shares I was at a loss as to how to proceed. The message I received when I attempted to view the file on the 'server' was simply that I did not have permission to access the files or insufficient memory.
On investigation of the registry on the 'server' the key IRPStackSize did not exist so this was created with the size set at 16. Following a reboot this had no effect on the problem! I have now reset this to 20 and the problem has been solved. I can now share the files as before from the XP Pro and XP Home systems.
Incidentally before I discovered this problem I had upgraded my Vista system to Windows 7 Professional and this is when I first discovered the fact that this could not share the files on my 'server'. This issue has also been fixed and this can share the files with Homegroup disabled.

I just installed a trial version of Acronis 2010 on a Dell Dimension 4600 with original 80GB c: drive and two 500GB drives run in RAID 1 for the d: drive. Sharing files with a Fujitsu laptop - was unable to access the shared folders and got the offending message. Decimal 16 and 17 did not work. Decimal 20 worked.

I Have both Norton IS 2009 and Acronis installed on my 2 desktop computers. I wanted to install Acronis on the Vista laptop and create and save the image to my older computer desktop for storage through a network. I could make a connection to my Vista laptop using my desktop XP's but it couldn't connect to my XP Home desktop. I did as this thread said and input a value of 16, that did not work, I put in the value of 22 and everything is good. Now all 3 of my computers will network properly.. Thank you very much.. :) I spent about 2 days trying to figure this one out...

I ran into this problem on my three computer network that worked fine up until a short time ago. Adding the IRPStackSize Dword (there was no such item in my registry and setting it to 16 decimal cured the problem. Information on this page suggests that it was Norton Internet Security 2010, which I had installed but then uninstalled a short while ago. With NIS 2010 installed, my local area network did not work at all. That's why I uninstalled it. I used the Norton Removal tool after uninstalling but I still think NIS 2010 is the culprit.

Has anyone had a similar experience?

This fixed it. I installed Acronis TrueImage Home 2010 yesterday to try it out. Shares that had been working on that machine for years (yes, literally) suddenly stopped being accessable from the other computers on the network.

I created the SRPStackSize parameter and set it to decimal 16 and all is well again.

I will uninstall Acronis as soon as I'm done entering this message. It was among three I tested. For those who want an alternative, check out DriveImageXML for cloning and image backup/restore. It's Freeware and is more flexible. For partition management check out EASEUS Partition Manager. It's free for home use and works really well .. easy to use and very flexible.

I rarely sign up to enter what I hope will be just one message but I really wanted to thank you for having the solution and having such a professional site. Well done.

...ken...

Hey guys I havent quite understand this thing due to my lack of English.

So I created IRPStackSize but I havent understand if the time I create it it should have a number.That means it was 0 and I made it 16,rebooted and nothing.

Also I havent unerstand what this means

Plzz help me cause I know I definitely did something wrong.

17 did the trick for me.. I had a suspicion it was Acronis but its getting so much mention on computer forums I didn't want to believe it. Everything works fine now. Thank you!

I read all of the comments and change the IRPStackSize ranging from 15 - 50 which does not seem to fix my issue.

Here is my situation.

I am running a windows home server with the following configuration:
Server OS: Windows Home Server (based on server 2003)
Hardware: Aspire easyStore H340 This is an OEM machine based on the Atom processor with 2 gigs of memory
The server is a headless unit with no access to a monitor port, keyboard or mouse. Yes I opened the computer and inspected the motherboard directly, nothing.

I am getting the following error message when I try to remote desktop in.

"cannot log you on due to the following error:
Not enough storage is available to process this command"

When I try to use the windows home server connector to log in it seems to process for a moment then does nothing and goes back to the login prompt.

What I have tried so far:
I removed the os drive from the server and connected it to another PC with keyboard and monitor and booted the home server from that machine. This caused the windows 2003 server to prompt me to register. I am assuming the reason was because it is some how keyed to the OEM hardware. I was careful not to load any new drivers due to finding new hardware the new PC as I didn't want this to affect the OEM server configuration where it might require user input. I registered the OS and proceeded to make the recommended changes here. I used the following settings for the IRP StackSize, 15,16,18, 30, 50 returning the drive to the OEM hardware server each time to try and access. None of these seams to work.

The strange thing is that I am able to access all the shares from my windows 7 machine with no problems. This seems to only effect the remote login. The problem occurred shortly after I installed freeproxy. I uninstalled freeproxy and set the IRPStackSize to 50 with no resolution. I turned off the firewall, "using bit defender 2010"

I am at a loss as to what else it can be.

I would appreciate it if anyone can help.

Excellent fix! Thanks.
This error occured after installing Acronis True Image Home 2010.
I set the value to 20 and I am able to share the pc on my network again.
Good work.

I have three xp computers on my network. All have Acronis & Norton installed. I keyed in the above(abbreviated message) when I could not share on one of the computers.

I had to expand the stack to 22, but it worked very well. I am impressed by this site.

You guys rock! This error just started popping up after 2 yrs of hassle free file sharing between XP Pro and Vista.

Uninstalling was not an appealing solution. I tried just adding the registry key IRPStackSize (mine didnt exist at all, let alone have a value, i set mine to 22 since that seemed to work for a poster using a similar set up to mine) and rebooted "Machine B".

Went back downstairs to Machine A and entered my path \\MachineB\blahblah and it connected in a snap. Just like the good old days.

So looks like I got it solved without uninstalling anything.... so far :)

I am now making a donation because this was the fastest resolution to any Winblows problem like this - and there have been tons - EVER!

Thanks again.

That was definitely the culprit. Installed it Friday to clone my drive and "not enough storage." Added the IRPStackSize DWORD 0x0000000f (16) parameter and its all working again. Thanks.

I have 4 computers in my home network. All use XP, the one I call "the server" is tied to our large format printer, and serves as a print server, and backup storage. I recently upgraded the size of the hard drive and used Acronis to clone the new drive. It wasn't until I needed to move some files to the USB external drive attached to "the server" did I notice that I could see "the server" from every other computer, but could not get onto any drive, and would get the error "not enough storage space"... I tried everything, then I found this page, late last night. I had to wait till I got home from work this evening, but all I did was to remove Acronis, and VIOLA' everything worked fine again. I did not have to edit the registery....thank goodness for this site... My advice to Acronis users is to install, use, and remove.

Acronis TrueImage & 16 is the go.
Thanks!

Didn't realise that Stack Sizes were an issue any longer. Used to set them back in the dream time but have thought nothing about them until now.

Norton will never be an issue with me for problems. Will not even look at a computer, let alone touch it if I so much as hear that N word.

This tip worked for me. The most important part of the tip is that the problem is on the computer where the share is. For me the IRPStackSize on this computer was already set to 18. I changed the 18 to 22 and was able to share all folders.

I have had three computers networked (Ethernet) for the last six years (different machines at different times) one with Win98 and all the others with WinXP (various SPs). NEVER saw this problem before now. However, I started using Acronis last year in the Seagate version and then (foolishly) purchased the full Acronis version and then upgraded that. I recently installed the Acronis product on my newest machine after which my sharing problems began. This is what made the tip so valuable - who would have guessed that the old computer was where the parameter needed to be changed! This seems to be fixed FOR NOW. But judging from my experience (18 did not work) and from some of the later posts, there is likely more going on here. I sure would like to find a less troublesome replacement for Acronis for imaging though. Have you ever noticed how many processes and registry entries Acronis puts on a machine?

P.S. At the same time I am wrestling with the sharing problem, I noticed that on my new powerful Workstation (with very little software yet installed) that I started getting freezes sometimes when I tried to clear the Taskbar Start Menu. Instead of clearing in a few seconds (at most), it was taking up to three MINUTES and sometimes required halting Explorer to clear. This weird behavior also began with the installation of Acronis. The system is still sick and I plan to uninstall Acronis (if one can get a clean uninstall with this product) and see if this improves the Start Menu clearing problem.

Thanks. It worked for me. I placed a decimal value of 25 in Vista (as the server), and XP Prof is the connecting client.
I only experienced this problem after installing Norton Internet Security 2009 yesterday.
The day before installing Norton, I was focusing on this error "the server cannot perform the requested operation" in the same XP machine, I installed LLTD in XP client and still observing, but it seems to be working now coz I haven't received that error "the server cannot perform..." yet as it was replaced by the error "not enough server storage." :-)
For those having an error with "the server cannot perform..." you may want to visit this link http://www.itropics.net/index.php/computers/networking/87-lltd-installat...

Hey guys, thanks everyone for useful comments. I did finally manage to solve this server strorage problem. From my Windows 7 machine I was trying to map the network share on my Windows XP machine. I have Acronis True Image (which I passionately love!!!) installed on both machines. I was playing around with this IRPStackSize entry on my Windows 7 machine and it just would not work. I started by 15 and went as high as 50. No chance!

When I almost committed suicide of frustration that I would have to remove the True Image, it just came across my mind that maybe I was fixing the wrong side. I did indeed!!! As soon as I set the IRPStackSize parameter to 18 on my Windows XP machine, I could map the network share. Wow! Thanks a lot for this discussion!!!
