Here's a link about that file name:
Did you recently install, or uninstall, a new program which is related to AT&T?
Have you checked to see whether a file named: "NetGina.dll" is on the computer? Do a search for it.. If not found, then you need to eliminate any registry entry which is calling for the file.
If it IS found, and the file is legitimate (not a virus), then it may need to be registered. (Scan the computer for viruses and malware first.) Open a command line, then type the command below, then press the "Enter" key.
Hope this helps.
I get the above error message above when I rebooted the Laptop after downloading a Win XP update. I saw a fix on the MS wwebsite which asked me to hit F8 to go into advanced start up and start up using "Last known good configutration." Tried this but still get the error message. I can however start in safe mode. I have the XP setup CD. Please help.
