Access to the path is denied: Assembly Permission Problem

Charles Leonard

I have a web service running impersonation of a domain account on Windows
Server 2003. I need to access a share which the Web Service classes,
themselves, appear to be able to create and access. However, when an
assembly (that is in the GAC, strongly named, etc.) is called to process the
file, I receive the message: "Access to the path is denied." This
installation works fine on Windows 2000 and Windows XP Professional.
However, Windows Server 2003 appears to require more security settings.

I think this has something to do with the Global Assembly Cache and trusted
assemblies. Although, I don't know for sure. I am unable to specify the
assembly as "Full Trust" through the "Microsoft .NET Framework 1.1
Configuration" tool as I receive the error "Unable to add the selected
assembly. The assembly must have a strong name (name, version and public
key)." I read in one of the newsgroups that "caspol â€“af" could be used.
This didn't help eitherâ€”it just stated: "ERROR: Unable to load assembly".

Does anybody have any ideas regarding what I can do to get the assembly to
read the share drive file properly?

Any help will be greatly appreciated.

Thanks.

Are you sure this is not related to configuration of delegation?

Even if the logged-on-user has access to the share, a process running-as or
impersonating the user does not, by default, have the same level of network
access.

In Windows server 2000 domains, delegation is either on or off for each user
account.

In domains raised to "Windows 2003" functional level it can be configured
for each server/service for each user.

Try following KB articles for more info
http://www.microsoft.com/technet/pro...5631c389f.mspx
(or search google with - including quotes - "Allow a user to be trusted for
delegation")

Thanks for posting your solution. I can see your point about new threads...

Impersonation is associated with a thread.
A new thread inherits the security context of the process - not the thread
that starts it.

If you need to impersonate on a new thread I guess you can pass the token
across.
