Strange VPN problem

I have a really strange VPN problem. I'm not sure whether this is server- or
client-side problem, I decided to post this here first.

I have a Windows XP Pro workstation at home and I used it to VPN into 2
different SBS 2003 networks. It worked just fine for a couple of weeks. Now
I can still connect to both networks (one at a time, of course) but I can't
browse server resources on the other network.

When I first connect, then do Start -> Run -> \\server it says "element not
found" (the error message was in Finnish, so this propably isn't the exact
translation).

I can ping SBS server by name (ping server.domain.local) or IP address.
Remote desktop also works just fine. I can use IE to go to our offices
printer web adminstration so I guess the VPN is sort of working. But I just
can't use servers shared resources. It worked before, now it suddenly
doesn't. NET VIEW shows only my computer. NET VIEW /DOMAIN:<domain> says
error 6118.
When I try to access a shared folder, I get "element not found" (or whatever
it is in English) but nothing shows up in the client computers event log.
Instead the SBS server security log has six of these errors in a row (they
appear again each time I try to access a resource, not when I make VPN
connection):

Event Type: Failure Audit
Event Source: Security
Event Category: Logon/Logoff
Event ID: 537
Date: 31.1.2006
Time: 2:46:29
User: NT AUTHORITY\SYSTEM
Computer: SERVER
Description:
Logon Failure:
Reason: An error occurred during logon
User Name: (E-Mail Removed)l
Domain:
Logon Type: 3
Logon Process: NtLmSsp
Authentication Package: NTLM
Workstation Name: WORKSTATION
Status code: 0xC0000225
Substatus code: 0x0
Caller User Name: -
Caller Domain: -
Caller Logon ID: -
Caller Process ID: -
Transited Services: -
Source Network Address: 192.168.0.22
Source Port: 0

However, when I VPN to the other SBS network everything works just fine.

I have tried to delete the VPN connection from network connections and
create it again. I also tried using the connection manager from the remote
web workplace.

I was thinking that maybe this is related to my account somehow, and tried
on a different computer. It worked instantly.

The client has nothing special about it, and there is no spyware/viruses or
any firewall software present.

At the same time there are about 10 users which use VPN to connect to this
network every day without any problems.

So, in a nutshell: one specific Windows XP Pro client can't browse resources
on one specific SBS 2003 server. Use different client _or_ server and it
works.

Any clues?

it could be the WINS issue. can you net view \\remoteIP or net view \\histname.domain.local?
