I cannot publish a map service because the PublishingTools service is stopped. However, when I try to start the service, it hangs, with the message "System/PublishingTools service is starting..." until I get a "Service startup timeout" message. Any suggestions? Someone posted a similar issue on gis.stackexchange here, but the question was left unanswered. The Server Manager is on Windows 7, the browser is IE, and Windows Firewall is off.
