New Windows 2003 Small Business Server
New switch installed (problem existed before this change)
20 Windows 98SE clients and 2 XP clients.
Users loose connection to the server. Open a file , work on it and then cannot save it.
Sometimes cannot print after printing most of the day.
Seems that when these problem manifast then Internet connectivity also lost.
Outlook 2000 takes about 90 seconds to send a new mail to Exchange. Don't know if these are related.
Would like to reach a stable working environment. System was set up by MS Gold partner MCSE's.
Any help appreciated.
