Having a really weird issue in that users are having problems opening some Office files. Mainly this is seen in Access files. When the user double clicks the file to open it or uses a shortcut, the PC does nothing. Watching task manager I don't even see Access start.
If the user opens access first then opens the file, everything works.
things that I have tried:
Disable SEP (antivirus/firewall)
added ip of fileserver to local intranet zone (based off other solutions)
changed ownership to an effected user
changed security permission on file to Full Control for an affected user
Made a copy of the Access Database (Copy worked but doesn't really solve the issue.)
File server is 2008, all clients are XP sp3. Office is 2007 sp2.
