We are having issues with our windows clients (XP and 7) opening and saving documents. Occasionally the users will open a document make changes and be able to save the file. Usually they recieve a pop up that says either network busy or that the file is read only. Mac clients do not have any issues.
Server: Ubuntu 10.04.2
Open VPN: 2.2.0 and
Any help would be appreciated.

so the clients can connect successfully? IP routing works? how are the windows clients accessing files? via a Samba share? or directly to a windows file server? this sounds more like a Windows networking issue than a VPN issue.
have you tested that IP connectivity works ? tried to download a large file from the server?

Yes, clients can connect to the VPN, IP routing works and we are able to download large files successfully. Clients are accessing files via Samba.
Thanks!!

this is a very nasty problem to troubleshoot:
*) the vpn works
*) accessing files on the samba share works
*) sometimes you get 'network busy' errors
hmmm your best bet is to optimize the throughput and latency for your windows clients; what kind of download/upload speeds are they getting?
also, then the 'network busy' message pops up, what do the samba logs show?
