Any file named dns.exe is not visible to Windows 2000 Server

[tholmes]

This is the strangest problem I have ever seen. Server information below:

SERVER OS: Windows 2000 Server SP4 + All Updates
Server Hardware: Dual PIII, 1.5GB RAM, 5 HD's
Server Function: DNS Server, Web Server, Email Server

Issue: Any file named "dns.exe" on the server becomes invisible to windows explorer and every other program but the initial startup of the "DNS Server". This is causing several problems.

1. The MMC Snap-in for DNS won't work
2. I can uninstall the DNS service, but I can't reinstall the service because as soon as it reinstalls the DNS.exe file becomes invisible.
3. I have a hotfix from microsoft to fix the MMC issue, but it won't install because as soon as it extracts the dns.exe file disappears
4. Most importantly the DNS server does not function correctly.
5. You cannot view the DNS.exe file in a command window even if you use the /A flags
6. But if you try to copy or rename a file to dns.exe in a directory with a file that contains a dns.exe file already, it won't let you because a file already exists with that name.

Any suggestions will be appreciated. This is wierd.

HAve you checked for Spyware? There was a trojan masquerading as dns.exe out some time ago. Maybe your anti-virus on that server is flagging this as a bad EXE.

When DNS is installed can you access the DNS console from another computer?

I have check for spyware and viruses. I have tried to access the DNS console from another computer, but the MMC snap-in won't work.

Thank you for the suggestions

I don't know if thsi will help, but I have a problem with the file "Defltdc.inf". I found this out when I went to repair a server. When I tried to reinstall service pack 4 it would error out "cannot find file" I copied it from another server and as soon as I copy it to the hdd is goes away, even if I rename any file to that file it will delete itself.

Weird.

this is a hijack issue.
look to secure the server first. all ports. remove spyware using all software you can find. reapply all service packs.

or reinstall.

or call ms pss.
