  Access Denied System.IdentityModel.Selectors Reply Contact Hello Everyone, I am having some problems with a website I am trying to move from IIS6 to IIS7 (Plesk installed, it matters because this stupid panel does a lot of crap). To cut it short:   [UnauthorizedAccessException: Access is denied.

Seems like only if I set it up from Plesk it requires that. Anyway, how can I grant access so that the creation of that dll can take place, and if it's ok ?

  Re: Access Denied System.IdentityModel.Selectors Reply Contact To narrow down, try granting Users group with Read permission on C:\Windows\assembly and C:\WINDOWS\Microsoft.NET\Framework and apply to all their sub folders. Restart iis to see if this fixes the problem.

  Re: Access Denied System.IdentityModel.Selectors Reply Contact Hy, Thanks for the reply. I have set the AppPool to use ApplicationPoolIdentity and gived the Local\Users rights in the directory where the site is located and everything worked. So, looks like ApplicationPoolIdentity has rights in C:\Windows\assembly while the user that Plesk set for the apppool (by default belongs to IIS_IUSRS) does not. I have added the user used by Plesk to the Local\Users group but still no luck. Does AppPoolIdentity belong to an other group or has special permissions in C:\Windows\assembly ? I am reading about the new auth model in IIS 7.5 but can't seem to fully understand why with a normal user it does not work and with the AppPoolIdentity it does.

So, the IWPD_whatever that Plesk uses belongs to the psacln group. Than group had access denied on the dll and regardless if I added the IWPD user to the Users group it whoudn't change the access since denied rulez. Thanks for the suggestion, problem fixed :)
