Anyone seen this error after upgrading to w2k3 sp1?

Windows cannot load extensible counter DLL BlackBerry Router, the first DWORD in data section is the Windows error code.

If I had to hazard a guess, I would say that your registry setting or sub-keys for the BB router may have been altered. Is the BES functioning as normal since the SP1 install? Is this a distributed install with the router on a separate system?
Try loading the router service on a separate system and have a look at the registry keys to whats different.
Usually as a precaution, sometimes if I remember, I export the registry keys just in case things go awry.

Error "Windows cannot load extensible counter DLL BlackBerry Router, the first DWORD in data section is the Windows error code." Any ideas what happen and any resolutions?
