Hi there

There is a formatstring bug in Compaq HTTP Servers. [in <!.DebugSearchPaths>?Url=> requests]

The HTTP server runs with LocalSystem account.

Versions: All versions i have tested had this formatstring bug.

To be shure that it wasn't allready fixed, i downloaded this new version.. Insight Management Agent
