Error calling unmanaged dll from webservice

[vikrantca]

Hello,
Iam trying to write a webservice that loads a managed c++ library which in
turn calls an unmanaged dll. I keep getting the error given below.

Also tried the following:
# Disable indexing service.
# Disbable firewall and antivirus
# copying the required unmanaged dll's to the bin folder

The error occurs only when Iam using this particular managed c++ dll which
calls an unmanaged dll.

Any help is very much appreciated.
thankyou.
