Open centera pool from webservice

Hello,

I can't acces/open a centera pool from a webservice when calling the function Pool.open.

It works fine from a windows service, but not from a webservice.

The windows service uses the same program code as the webservice.

Does anyone have experience on this subject?

Has it something to do with the application pool from the webservice, security,..?

Thank you.
