During a denial-of-service attack, the Transmission Control Protocol (TCP) stack may use up all the memory on the computer that is being attacked.

When this happens, if you use the PING command, you receive an "out of quota" error message. If you run the Ipconfig.exe program, you receive an "application could not be initialized properly" error message and a run-time error. You cannot gain access to the Network tool in Control Panel. After the attack, you cannot start any programs in Windows 2000. The computer becomes useless as a network server.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
