Question: What are the permissions needed for users IIS_IUSRS and IUSR?
Answer: Below is the list of permissions you'd need to add to these two users (letter drive may different). Simply access the KServer and make sure to give the below Kaseya folder(s) full permission (IIS_IUSRS and IUSR):
Path: C:\Kaseya\DBInstall
User Account: IIS_IUSRS
Permission: Add Full control
Path: C:\Kaseya\MessageSys
User Accounts: IUSR & IIS_IUSRS
Permission: Add Full control
Path: C:\Kaseya\UserProfiles
User Accounts: IUSR & IIS_IUSRS
Permission: Add Full control
*may take longer but please make sure it completes.
Path: C:\Kaseya\WebPages
User Accounts: IUSR & IIS_IUSRS
Permission: Add Full control
Note: If after adding these permissions you're still facing issues with any VSA page throwing the "Oops..." error message, submit a ticket for Support to review further, via this link.
