I have a Windows 2003 Standard with some folders shared correctly and
Another Windows XP machine on the same network attempts to access this
computer through \server01 . They get the following error, "The user has not
been granted the requested logon type at this computer" blah blah. As we all
know, this is usually a problem with the local security policy.
So, I went in to the local security policy and lo and behold, "Access this
computer from the network" was blank. So I added "everyone" just as a
catch-all. Hit OK, the computer was able to access this share... no problem.
After some minutes I got the same problem again. So I go in and look and
"Access this computer from the network" is blank again. I go in and reset it
to allow everyone, close out of the policy, go back in to make sure it's
still there and it is. So I close out, give it about 30 seconds, go back in,
and it's BLANK!
I'm thinking virus/trojan/spyware, so I check the processes running on the
computer. Nothing real out of the ordinary. McAfee VirusScan 8.0i, Symanted,
NOD32 all updated. Run a full scan and it comes back clean. Installed
Microsoft AntiSpyware and it comes back clean. But for the life of me I
cannot get the local security policy to keep this setting.
I found something about Win32/Exploit.DComRpc.B trojan. I can see besides
the blank policy I cannot activate automatic updates because it is disabled
again, and some registry Keys that are changed too.
Does anybody know if there is a hotfix? any advice will be appreciated.
Thank you.
