Hi, i'm trying to fix a neighbour's laptop who's running xp home, 2.8 gHz and 128mb SDRAM. When they click on their logon icon, it shows that 4 .tmp files are "not a valid windows image. Please check these against your installation diskette". The message box reads "ndis.exe - bad image" at the top. The four files with problems are: nta1.tmp, nla3.tmp, gpa4.tmp and hxa5.tmp. Any help on this would be appreciated as we dont know what the problem is! Thanks for your time! - Andyram2k Alcohol and Calculus don't mix, never drink and derive

A Google search for ndis.exe produces a lot of results, but the others don't. Don't know if this will help or not.

i did a system search for it and it's stored in c:\windows\system32. Still not sure! Thanks for your time, -Andyram2k Alcohol and Calculus don't mix, never drink and derive

Is the problem they're having that they can't log in, or what? It's not in my c:\windows\system 32. What if you just deleted them all (after copying them somewhere) and see what happens?

Yes you can copy these files into a new folder and then try deleting these files. Since these are .tmp files,deleting them shouldn't make any difference. MS Tech support

I went through my registry and deleted all the ndis.exe keys. I then rebooted the pc in safe mode and deleted the ndis.exe file and emptied the recycle bin. Then I rebooted again and the issue was gone. Thanks a bunch!

My mom had this problem as well, "ndis.exe - Bad Image" message at boot up. Without me working directly on her laptop (a fairly new Toshiba running XP Home) she ran a Norton AntiVirus scan, and changed the option from "Deny access to the infected file" to Automatically repair the infected file (recommended)". This setting is found under Options/System/Auto-Protect/How to respond when a virus is found. The problem went away. So, I'm not sure what fixed it or even what caused it, but her's was a simple fix. shubb
