We have about seven computers that access their data from our central server. They all use and save data directly to the server hard drive. The server is just a dell PC running windows server 2003. Last week One comp couldn't connect to the domain so I logged into the server to troubleshoot. First off i noticed some icons on the desk top called Mail Bomber along with other supporting files. I went to get Windows defender just to run a sweep and had to restart computer. After restarting I could no longer log in with my password, I still cannot today. Most of the workstations can still access their files from the server, and I can log in as Admin from a workstation and look at the server's files. And now some of the workstations are asking to verify credentials "lock and unlock the computer" I forget the whole message. I was able to get in to the server through safe mode but that's it. 2 workstations are using the same login and 2 others share the same Admin login that i use for the server. Also several Shorcuts on the workstations have had their target changed to random folders. I don't know what to do.
