Have a site to site vpn from a remote office,

The Network topology is this
 
Main Network --> cisco pix 501 ----->router ---->internet <------Router <-----Cisco pix 501 <--- remote network

We have an NT domain with NT servers and 2003 member server as a file server and Terminal server.

My problem is I can log-on with a 98 machine and browse the files, but with an xp sp2 Machine I cannot browse the mapped drives or via IP adress\share or Netbiosname\share.
both wins and DNS are correct, I have flushed dns and registered dns.

I can get to the top share level \\computername but cannot open any folders

the Cisco site to site is running at 3des 1024 md5 I have tried running it at 768 made no difference

any idea's

I think SP2 shut the door to NTLMhash authentication: You can revert back.

Thanks ChiefIT,

I tried that but to no avail

but I do get some more errors like trying to to get onto the mapped drive I now get  the connection is already connected but cant still browse,

But I have found a workaround now , to do what I had before to run a pptp vpn, this now works and customer is happy it is working.

Thanks for the advice , pointed me in the right direction.

Thanks again

Was the work around related to the browser service. If so, we can fix that as well.

Sorry I haven't checked in with you for a while:

I wanted to point out some things that you may run into in the near future. Your VPN connection will probably only work for so long when using netbios across it. I have seen it work for a while and stop all of a sudden. So, you might familiarize yourself with How Netbios works and is not routeable between sites. Then, consider putting in a WINS connection between the sites PDCe's for Netbios.
