I have a mixed Peer to peer network standard 10/100 ethernet, TCP/IP, no DHCP, with 1 Win2k, 3 98se, 3 XPpro and 4 win95 PCs. One of the XPpro PCs is set up as a "file and print server". The main application used is Excel. There are literally thousands of files within dozens of folders on this XP pc. One PC in particular accesses it all the time. The XP pc acting as a "server" is brand new. Previously all of these Excel files were on one of the other 98 se PCs. We copied the files over to the new XP pc.
Most everything works well, except the 98se PC has occasional problems browsing the folders with the excel files in them. It's generally first thing in the morning after the PCs been on all night and several times throughout the day. When the user opens Excel and the open file icon, the dialog box appears. He navigates through a couple of shortcuts to get where the files are and then it stops, like its trying to browse and gather info on the contents of a folder. Usually it stops responding, but the rest of the PC continues to function. I added NetBEUI back into this PC after removing it from everyones installed protocols. NetBIOS is enabled on all PCs. After adding NetBEUI user reports some improvement, but this may be a placebo effect on the user.
He usually waits for minutes before just rebooting the PC
