HTTP 500 error while browsing http://localhost/xmla/msxisapi.dll - XML SOAP

Can you try switching the virtual directory to use Low Isolation instead of
Medium/High? I'm not sure what the cause is, but it looks like your
out-of-process COM host has some problem...

Thanks,
Akshai

Akshai,
Thanks a lot. Changing the security to low worked. How will this
effect the security of our application? We have this server anyway
inside the firewall?

Thankyou for your time.

Thanks,
Narendra

Low isolation is a little faster, but the risk is that if the ISAPI DLL
crashes for any reason it will bring down IIS and you will need to restart
it. Medium/High isolation applications run outside the inetinfo.exe process
and therefore application errors in them do not affect IIS.

You could try to fix the Isolation problem as well but I can't offer much
help there -- perhaps searching the IIS newsgroups may find you an answer or
you could try posting a question to one of them.

Thanks,
Akshai
