My company is upgrading both pc hardware and OS at the same time. We are going from Pent 100mHz/WIN95 to Celeron 500mHz/Win2KPR. This upgrade is taking place in all 3 of our locations and each location has gotten the same type of error but at different times. During this upgrade I am occassionaly getting the error message "Unable to logon. Net logon service not started". This issue is happening more and more with the amount of pc's that we are rolling out weekly. The only fix that we have found it to reclone the pc. One site is using CAT 5 and the other two are using CAT3 cabling. Does anyone have any other suggestions?
