Maybe you have a thought on my : Unknown tranform has been encountered   Problem???

I?m using WSE 1.0p1/.NET 1.1, and signing and verifying xml documents not SOAP.  So I?m using WSE?s SignedXml and getting this exception.

My guess:  machine.config doesn?t have the transform implementation class found for all the namespaces in the <signature>.   BTW, I?m on XPsp1 and our IT department creates the XP image.  There might be something they strip out of XP??   I did check what CSC?s are install and the MS_ENANCED_PROV seem to be installed.  But I wouldn?t know if any are missing.

Although I can sign a doc, I can?t validate the same doc??

I started guessing at the transform namespace to impl classes in my machine.config (end of email).
Any thoughts??

Thanks Curt
