Windows Server 2003 hacked by the Chinese?

I have a Windows 2003 server and I think I have a security issue with it. The default language was mysteriously changed to Chinese, I changed it back. I keep seeing lots of connections on my SonicWall to port 80 from all kinds of IP's from China. I already blocked lots of Chinese IP ranges on my SonicWall. I wish there was a network group object that i could import that contained all the country IP ranges of all the bad guys. At this current moment I don't see any Chinese connections but I'n not convinced this is fixed yet.

I noticed that the IUSER_WEB was a member of the Administrors group which sounds very fishy. I've disabled the IUSR_WEB account for the time being. This server also just passed a malwarebytes scan test and its all up the date on Microsoft updates. What is the default security assigned to the IUSR_WEB account? I need port 80 open on this machine since it does host a small webpage. Anything else I should be looking at?   Thanks!

I think that the only safe thing to do is to wipe and restore from backup or wipe and rebuild. You can't trust anything on the system, not even GIF files.

Agree with the comment above.  To prevent a reoccurrence, ensure that your server is fully patched and antivirus current before presenting it to the Internet again.
