Removing manufacter and version #'s from IIS services

Genericizing Internet Services in Windows 2000

Disabling Windows File protection:
-sfc /cachesize=1 (really just setting the cash size to 1 meg)
-del everything in C:\WINNT\system32\dllcache
-del the proper service .dll from C:\WINNT\ServicePackFiles\i386 (w3svc.dll or ftpsvc2.dll)
-reboot

Changing version strings in .dll files:
-copy the required .dll to a .bak file
-use a hex editor (ultraedit is nice and you can dl it) find microsoft in .dll (w3svc.dll or ftpsvc2.dll) and replace it with something random(there are 2 occurances in one of the files), replace version number too, windows will ask you to insert the cd-rom, tell it to not replace the file
-restart the iis services

Testing your change:
-telnet 127.0.0.1 21 (for ftp)
-telnet 127.0.0.1 80 (for http) hit enter a few times
-neither service should say anything about microsoft or a version number

Re-Enabling Windows File protection:
-sfc /cachesize=50
-sfc /scannow
-reboot
