A Cause for HRESULT 0X80131468 when accessing IsolatedStorageBackingStore

Question

The scenario I am facing is that I have an ASP.NET web service (.NET 3.5) running on an W2k3 server which is using the CacheManager/IsolatedStorage store to store a persisted state variable. This configuration has been working fine for quite sometime until we changed the physical machine. Now whenver the code that accesses that value runs it throws an IsolatedStorageException (Posted below). As I understand it the user/assembly store is what is being accessed and the executing user is a member of the local administrators group. Does anyone have a suggestion as to what privilege is missing?

Error

Unable to create the store directory. (Exception from HRESULT: 0x80131468)

Answer 1

The root cause of the issue is that the account which the web service was running under did not have a local user profile created thus the user assembly store didn't exist. The simple fix was just to logon to the box with the service account.
