Accessing shares on a 2003 DC using VPN (URGENT!)

Could you give any more information?  

Were you previously connected to the shares on the client without VPN but then tried to reconnect later through VPN?  

Is it saying that the shares are disconnected?

Yes, I was working about a month ago, then it just stopped (not sure when).  I can browse to all other workstations and servers in the domain except the 2 domain controllers.

Yes, I had the H: drive set up on various remote users and all of a sudden the stopped working.  I am occasionally doing things in the GPOs, but not sure what that would have done.  Now, going to either \\servername or \\ipaddress will not work on the 2 DCs.

what is the error message, any events ?
are these shares accesable from the Lan ?
can the other domain controllers browse these shares ?

I found what I think might be the problem.  Yes, all sharing between servers, workstations and domain controllers works fine.  It is just a few laptops that had a mapped drive previously for some reason could not get to the DC shares.  I have just discovered that if I disconnect the old mapped drives, reconnect and click the link to "Log on as a different user" that it works.  My issue now is that when they set it to "Work offline" and use the synchronization feature, the OLD H:\ drive is still in there and fails, but the new one works fine.  It appears to be a caching issue for synched drives on XP.  Where is the place to remove the synched drives no longer needed on XP.  Even though I remapped H:\ to a different share,  it still wants to synch the old H:\ drive.  It shows up in the icon in the systray that is the synchronization alert and has \\servername\oldshare that fails.  How do I get rid of that?

That is it.  For some reason, I think they changed their password and the shares lost perms.  Thanks for the help!
