Solution

There are numerous issues that are known to cause this issue.

• Group Membership:
  Verify the IUSR_<machine_name> account use by ClearQuest under the IIS manager is not a member of the group "Guest". Guest membership is known to restrict access permission's, which can prevent the ClearQuest web from working correctly. TheClearQuest Administrators Guidespecifies that the IUSR account should only be a member of the "Users" group.
• Incorrect IUSR password
  Reset the password for the IUSR account. If the password has been reset, or is incorrect, the ClearQuest web server will not start.
• Event View logs are full
  Clear out the Event Viewer log. If the log files on the Windows® web server machine are full, the ClearQuest web server will not start.
  To clear the event log and restart the Web server:

1.     Go to:Start > Programs > Administrative Tools > Event Viewer

2.     Right click the System log and select Clear All Events.

3.     Right click the Application log and select Clear All Events.

4.     Right click the Security log and select Clear All Events.
NOTE:Selecting the "Over write as necessary option may help prevent the logs from becoming full" .

• IIS Version
