ActiveX error -2147023149 in LabVIEW 7.1 but not LabVIEW 6.1

This is an interesting problem. There is a Tektronics ActiveX control
for a TLA700 that works flawlessly in LabVIEW 6.1. An upgrade was
made to LabVIEW 7.1 and when simple calls are made to this ActiveX
component it throws the error "-2147023149". On google I found:

-2147023149 == "The authentication service is unknown."

A final note is VB and VC++ have no trouble using this control on the
same machine.

I have searched every possible resource availible and am getting no
where on pin pointing where this error could be coming from. Anyone
have any ideas or even seen this error before??

Hi benv,
 
I can see that this problem seems to have come up slowly over time.  By searching for it I can also see that the problem occurs in Visual Basic and Visual C.
 
Historically the problem has only occured with computers running LV 7.1.  No customers have reported it in later LabVIEW versions, but they also haven't confirmed that the problem went away with LV 8.0.
 
You may want to look at this KB to see if it is relevent:

Tell me if it solves the issue.
