NT4 index server asp error 0177 for ixsso.dll

[rvj]

Im attempting to test an old NT4 server with IIS and IS . All the standard
IIS services work
fineand even the IS app seems to be indexing without generating any event
log errors.

The real problem seems to be the IE query interface to ASP

Has any body had a problem running index server query.asp?

I keep getting asp error 0177 on createobject (ixsso.dll) which I understand
means that the dll has not been found even though it is in the directory
c:\winnt\sytem32

If I then try to register ixsso.dll from that directory then I get
0x0000001f registration error

Any clue what the problem actually is and how to resolve it?

PS Have uninstalled index server and re-installed but produces the same
problem

Thanks
