Last one week I was facing problem with one of our server. Whenever I login to that server through RDP it is just showing “Applying Personal settings” And it is hanging . Even I can’t access the shared folder of that server. I searched for a solution but every where its saying that it is a problem with user profile issue and DNS issue. Both may be the reason for this issue. Because I got this same issue with one windows XP PC. It was a problem with wrong DNS entry. That time windows will load after 1-2 minutes. But in the case of a user profile corruption it won’t login.
I checked both options in this server. But it was not the problem in this server. Finally I came to one Microsoft knowledge base and understood it is a problem with Vulnerability in Server service could allow remote code execution.
About this vulnerability :
This is a remote code execution vulnerability. An attacker who successfully exploited this vulnerability could take complete control of an affected system remotely. On Microsoft Windows 2000-based, Windows XP-based, and Windows Server 2003-based systems, an attacker could exploit this vulnerability over RPC without authentication and could run arbitrary code. If an exploit attempt fails, this could also lead to a crash in Svchost.exe. If the crash in Svchost.exe occurs, the Server service will be affected. The Server service provides file, print, and named pipe sharing over the network.
