Are you using BizTalk 2004 and getting
an error stating that “Specified cast is not valid”? I’ve been getting this when trying
to create a port on one of the BizTalk workstations I’m nursing and finally tracked
down a resolution in a KB
article. It describes it as a solution for a different problem, but I’ll bet my
socks that this will cure it.
Update: Yup .. that worked. Seems like the COM+ Rollup package
will cure a number of ills
