If first posted this in the Network area but, I've isolated the issue to Office 2007 and Windows 7.
I have recently set up a new network and 4 desktops for a client. The server is running Windows Server 2008 and the desktops are all running Windows 7 with Office 2007. When ever the client goes to save a Word or Excel document to a network share, the applications takes 20-30 seconds to save the file...even very small files. Opening files is quick and other applications (database) are performing well. As a test, I attached a PC running XP and Office 2003 and attached to the network and it's performance is normal (i.e., saving is very fast.)
I have read in other forums about poor performance when there are mapped drives that are no longer active. This is not my case as this is a brand new environment and I have removed all mappings and tried saving directly to the \\server\share\. Also, notepad and word pad do not have the same issue, it seems to be the way Office is interacting with the network. Any thoughts?
