We have a mixed mode Network. Windows NT 4.0 Server, Novell Netware 5.1, Windows 2003 Server. Ever since I began to change the Subnet mask on our PCs, I began to notice Network slowness.
However the slowness is isolated to only Windows Workstations. The Netware File Server is unaffected by this network slowness. What happens is if one tries to access a mapped network drive or open a word/excel document, there is a 12-14 second delay. Then after that initial attempt, one can open up that mapped drive or any other document within that drive very quickly.
But, the problem comes back after 5 minutes. Its is only on Windows Servers, NT or 2003 Servers. I think it must be ties to Active Directory and Authenticating to these different servers.
Anyone any ideas?
