We have installed file server and Domain on windows 2003 R2 SP2. All user have joined and all map ready for store data and E-mail.
may 1 month a go We don't know why. there are sometime clients when they start open outlook(2003,2007), the outlook can't fine or access denied on the file stored in map drive. but folder map drive can access to file normal when explore on it. But when we try use remote desktop to remote to file server or DC until it was connect and then outlook work and can access normal.
I really don know what something occur with my server and remote desktop with mail client that access file on file server.
For security use Bit defender license in network
Windows 2003 Standard Edition license
Thank you for your interesting and help.
