Hi,

I am getting the following error message when trying to access a WinXP Pro PC (DT1) from a Vista Laptop (LT) and another WinXP Pro desktop (DT2)...

xxxxxxx is not accessible. You might not have permission to use this network resource

Background: ONe week ago I had a C: drive failure. I made new install on new drive, it was a normal WinXP Pro install + SP2 and all other patches. MS firewall, AVG Virus scanner, MS Office 2003+ various update, plus a few other programs. PC (Dell 4550) sits on normal network with other PC's. No errors reports in Event logs, not other errors anywhere. Can access the internet okay.

On the internal network, with Vista LT and other WinXP DT2, sitting on DT 1 can see all other PC's (from the work group icon) and via their shared folders and can copy/move any kind of file. But when trying to access DT1 from LT or DT2 I get the message xxxxxxx is not accessible. You might not have permission to use this network resource.

I have Googled all today and have checked all the suggestions, registry entries, protocols load, set-ups etc. I have turned of the firewall/antivirus software and many other diagnostics, but cannot figure this one out - it has three people stumped here. What have we missed????

Any suggestions gratefully received, please.

Regards

Mike

Since you have done your homework, I am assuming that all of the machines are on the same workgroup and that File and Print sharing is enabled on each of the machines, have you checked the Share Permissions. Is Everyone allowed Full Control to the share?

Has NetBIOS been enabled in your TCP/IP settings?

Hi, been away for a while, I did not think that you had to have netbios enabled. My other PC's do not have this activated and they connect over the network okay!!!

Back to this issues again. Have rechecked and rechecked and rechecked and still can't seem to fix this, any other suggestions?

When you reinstalled your OS did you recreate the user credentials from the other machines?
This article might help you. It's primarily concerned with getting Vista and XP to work together, but a lot of the info applies to getting XP to talk to other XP machines as well.

I set up the reinstalled machine with the same settings as the previous machine, that is with simple sharing turned off but it did not require any further logiins. I looked at the other article and have done all of that and still have the problem.

Any other suggestions.

Is the behavior the same if you do a start, run, \\ipaddress and try to open a shared folder?

Hi, Yes it is the same no matter which method I try, I simply cannot access the XP PC from the Vista PC or other XP pc's on the same Network, same message every time. Running out of options to try here.

Ok, this should do it:
1. Click Start, click Run, type regedit, and then click OK.
2. Locate and then double-click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Lsa
3. On the right side, double-click restrictanonymous.
4. Make sure that the value in the Value data box is set to 0, and then click OK.
5. Close Registry Editor.
6. Restart the computer.

Let me know how that works for you.

Hi, many thanks for the info, but sorry to say that the value is already set to 0 (zero) in the registry. Any other suggestions.
