I recently switched from a Netware 4.11 server to win2k on a domain. All clients are windows 98. Used unc32.exe to uninstall nwclient. All clients have mapped drives to users files. Randomly have clients lock up when in Excel. One locks up when accessing My Computer. Also DOS porgrams. Accounting software is DOS based and on an NTFS volume. Manufacturer says its compatible with NTFS and usually works. Server came with the whole drive formatted NTFS and no way to make a FAT32 partition. Why would clients be periodically locking up? Any ideas. Most work well but just at times locking up. Never happened with Netware.
