I must regrettably add to the confusion...
this is, once again, a version issue.
in 2000, the tool was only called Reporting Service
SSRS 2005 requires the timeout to be left blank,
SSRS 2008 requires the timeout to be 0,
Please include which version is being referred to in the QotD.
Space, the final frontier? not any more...
All limits henceforth are self-imposed.
