64-bit XP Pro PC can't see 32-bit XP Pro PC

Sat, 2009-08-08 10:44 by abingdon3 · Forum/category:

I've recently built a new PC and installed the Win XP Pro 64-bit operating system. I have a 32-bit XP Pro PC that I want to use for backup. Both PCs can access the Internet through a Linksys WRT55AG broadband router.

The XP Pro 32-bit can see the XP Pro 64-bit box by means of a Windows Workgroup. However, the 64-bit PC can't see the 32-bit PC. The 64-bit PC uses a Kaspersky Firewall, while the 32-bit uses a McAfee firewall, but it doesn't seem to matter whether they are turned on or not. (The MS firewall is always off on both PCs.)

I tried setting up a wireless home network to see if the two machines can see each other, but that didn't work. I've activated the "share" features on certain folders, but that doesn't help, either.

Does anyone have any suggestions?

Thanks in advance,

Roy

PS: The 32-bit PC uses a Linksys WMP300N card while the 64-bit uses an MSI PC60G card.

Call the share directly

To be able to see another computer and its shares in a Windows XP network depends on the Computer Browser, a notoriously unreliable service of Windows XP.

Whether the computers run on 32 or 64 bits does not matter.

I would first try to call up the share directly. Just type \\computername\sharename into Windows Explorer to check whether that works, or even just \\computername (replace these words with your actual names). If that opens the share or shares, do it that way. You can use the net use command in a batch file to reach the other computer.

If that doesn't work, then there is a different problem, but let's check first things first. Also there are ways to troubleshoot the Computer Browser service. There are tricky interdependencies between that and the Windows Firewall.

Thanks for the quick

Thanks for the quick reply!

Today I tried to access the printer from the XP-32 PC by typing the share name: \\Win-XP-64\Printer2. The XP-32 PC does see the XP-64 PC, but none of its folders, files or the printer. The Windows Firewall is turned off, but the McAfee Firewall is on. I received the message: "Windows cannot connect to the printer. Either the printer name was typed incorrectly, or the specified printer has lost its connection to the server." There is no server, just two the PCs connected by a Windows Workgroup.

I next tried to access the Backup folder on the XP-32 PC from the XP-64 PC, using "My Network Places". However, I can't see the XP-32 PC from the XP-64. I typed in the location: \\XP-32-PC\Backup\, and received this message: "Windows cannot find \\XP-32-PC\Backup\. Check the spelling and try again, or try searching for the item by clicking the Start button and then clicking Search." That didn't work. (The Windows firewall is off, but the Kaspersky firewall is on.)

I then tried connecting with "net use \\XP-32-PC\Backup\" at the command line, but that didn't find it.

Yesterday, I tried using gpedit.msc in the command line, to bring up the "Windows Settings" box, and then tried changing some of the security settings, but that didn't work, either.

Any more suggestions?

Thanks for your time,

Roy

Use the Network Problem Solver

Problems like this are easily solved by the Network Problem Solver. Just fill in the form and read the results.

My first guess is that the firewall blocks the Windows networking ports, but the Network Problem Solver will show you most other possible causes as well.

Solution: Check Firewall Settings

First, thanks for your patience! :)

The problem was with the firewall settings on the two PCS.

On the Kaspersky firewall, I checked the Settings tab and then the Network Packets tab. There was a list of deniable sources with checkboxes. I unchecked these:

Remote desktop
Local Services (UTP)
Local Services (UDP)

Then, the 64-bit PC could easily see the 32-bit PC.

On the 32-bit PC, I loaded the Windows Firewall, went into the Settings and clicked the Exceptions tab. I checked "Remote Desktop". The 32-bit PC could now see all files on the 64-bit PC.

I then printed a test page from the 32-bit to the printer that is connected to the 64-bit. It printed OK.

I hope this helps somebody who has similar problems: Check your firewall settings.

Firewall exception for File and Printer Sharing

Sun, 2009-08-09 20:50 by admin

The firewall exception should be for File and Printer Sharing, not for Remote Desktop. I'm a bit surprised that it works anyway. But perhaps the other two exceptions, whose names I don't know, cover that.

File and Printer Sharing are

Mon, 2009-08-10 12:34 by abingdon3

File and Printer Sharing are enabled on both firewalls, but I couldn't connect the two PCs until I enabled the other services.
