Good Morning List, We have a simple small business network. One domain controller, one member server (accounting & bookkeeping) and ~25 workstations. Windows 2000 Server with Win2k & Win XP clients. I come in this morning and I start receiving complaints that users cannot print jobs from the printer that is installed on the member server. Upon investigating a little further I find that the backup job on the same member server failed. The reason being that the user's logon account for the backup service was rejected. Event log states that 'No domain controller could be contacted.' I know that this is not correct because everyone can login, connect to network shares (on the dc) and print (printers installed on the dc). No dns changes have been made. The only other event that was different was that we installed an ODBC driver on the member server yesterday. I have since removed it. I'm beginning to wonder if the nic has gone bad??? It has a green status light but. I tried disjoining the member server from the domain and re-joining but now it says it does not recognize the domain name. Any insight would be very much appreciated! Thanks Ron
