There are some known problems that can occur with a DDE server. Sometimes when closing the computer down, a message or pop-up will appear stating that the server can not be found. It comes up as the following message: "DDE Server Window is not Responding." One cause of this problem is a virus, but it is not the only cause. There can sometimes be a simple problem with the data transfer service
. also. The virus name is svchsot.exe. It is meant to mimic the svchost.exe application. There are also many other aliases and variations known for this virus including W32/Sdbot-UZ and W32/Codbot-y.The viruses are a form of malware, a worm or trojan that invades the system and allows a remote user to steal personal information through a remote backdoor. The viruses can cause a number of different symptoms including a slow moving computer, unexpected behavior from programs or applications, freezing, crashing, pop-ups and trouble closing down the computer. A virus or malware scan can detect the virus and wipe it from the computer on most occasions, however sometimes these viruses can not be found or detected by using an anti-virus program. In this case they have to be removed manually by deleting them from the registry. This is a risky process and should only be attempted by advanced computer users.The other cause of a pop-up window, with the same message that the DDE server is not responding, can be a common occurrence with data transfer servers and is no cause for alarm, even though it can be frustrating to deal with. It is often seen with netdde.exe when more than one data transfer is attempting to take place at the same time and they conflict each other. This can be solved by running msconfig and closing out or disabling any services/processes that are not needed. HP also offers help and advice on their website for DDE server errors.
