Hi Adam,

Does the user have all the required permissions (Add, View and Edit) on the SharePoint site?

Can you try recreating user's profile on that system and then ask the user to try accessing the form again? Also, what happens if the user for
whom the form access fails logs in into another system and then try accessing the form?

Hello!
I have an Infopath form published on Share Point Services server. The
SPS site is added to IE Trusted Sites zone. When some (<1% of
population) users open the form using a link to the template they
receive the "Insufficient Security Privilege" error message and the form
does not open. Clearing IE cache does not help. Making the form Full
Trust with Certificate generated by Infopath does not help either.
What can be wrong with the form/SPS that it returns this error only on
some workstations? The workstation environment is an enterprise Active
Directory with managed GPO so settings on PCs (both workstation and
user) should be the same everywhere.
Thanks for help in advance!
