Problem connecting to an IFD organization, can't open 'System.Web.RegularExpressions' RRS feed

  • Question

  • Hi,

    We have an IFD CRM 2013 SP1 that has been working but has now been moved to another VM. After this we can no longer connect to the CRM and get the following error:

    Could not load file or assembly 'System.Web.RegularExpressions, Version=, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. Either a required impersonation level was not provided, or the provided impersonation level is invalid. (Exception from HRESULT: 0x80070542)

    What does this mean and how do I fix it?

    I haven't been able to find much about the error on the web which is sort of frustrating. It feels like CRM has a never ending pool of errors to throw at you...

    I sincerly hope that this in not a case of "it is how it is" considering that we can't access CRM atm...
