I have a strange problem. We recently purchased a new dell power edge 2850. Its running windows 2003 ent, is our exchange server (ent 2003) and file server. we also have an older w2k domain controller in our setup. Since we have moved onto the new server, excel and autocad 2007/ 2006 have been having problems. In excel for some spreadsheets, if they save onto the network, when they open up the file again, the data has been damamged or corrupted. If they save on thier c drive, the data is fine.
With autocad with some drawings, when saved onto the network, when re-opened, the software needs to recover the drawing. Once recovered and saved, next time same again, the drawing needs to be recovered. If they recover the drawing and copy/paste onto the network, then all seems fine.
However we have other databases, sage and other files such as lotus and word, working on this server with no problems, and have no problems with our email system.
Heres what ive done so far : tried re-installing the problem applications, fully patched the applications, fully patched the server, uninstalled norton from the server, virus checked and spyware checked each problem machine and new server using norton and avg, adaware and spybot, all clean.
Any ideas what could be causing these problems?
