Jazz Team Server 4.0.2 not starting on Windows 7

Although it is not officially supported, i successfully installed RTC on Windows 7 several times. Always for testing purposes, of course. What problem are you having?

Did you tried start the server as administrator? (right click, Run as Administrator)

 Hi Supriya

getting a lot of access denied error messages on the Tomcat console, but cannot halt the same until the server restarted... end point.

We need more details on what you mean by "not starting" but here's a couple things that have caused me problems in the past

1. Tomcat starts then just disappears

The tomcat window should now remain open so you can see any error messages.
If it still does not remain open run server.startup.bat from an existing command prompt started as administrator.

2. Not enough memory. (You will need at least 8 gigs of RAM to run using the default values)
Change these values found near the bottom of the server.startup.bat script
set JAVA_OPTS=%JAVA_OPTS% -Xmx4G
set JAVA_OPTS=%JAVA_OPTS% -Xms4G
....
set JAVA_OPTS=%JAVA_OPTS% -Xcompressedrefs -Xgc:preferredHeapBase=0x100000000
to
