Symptoms

If you use the Internet Security and Acceleration (ISA) Server snap-in in Microsoft Management Console (MMC) to restart the ISA Control service, you may receive the following error message:
1053 - The service did not respond to the start or control request in a timely fashion.
When this occurs, you see in Windows Task Manager that Services.exe is using 100 percent of the CPU resources. Performance at the console is sluggish. Internal users may lose the ability to access the Internet through ISA Server. Internet uses may lose the ability to access any servers that are published by ISA Server. The server stops responding (hangs) for an indefinite period. You may not be able to shut down the server gracefully; you may have to force a restart by either turning off the ISA Server-based computer or unplugging it.
