After the Patch Tuesday releases from a couple of weeks back, Microsoft came out and gave a disclaimer. It revolved around warnings of known issues to support pages for the KB5006674 and KBS5006670 updates.  Microsoft highlights 0x000006e4 (RPC_S_CANNOT_SUPPORT), 0x0000007c (ERROR_INVALID_LEVEL), and  0x00000709 (ERROR_INVALID_PRINTER_NAME) among the issues that users may face once they have made the upgrade. The KB5006674 update is causing plenty of issues for the Windows 11 users, however, Microsoft announced that there are plans underway to remedy this whole situation. There are very few solutions to this issue, Microsoft has highlighted a plausible solution to this issue. Users updating to Windows 11 may encounter the following errors while trying to connect to a remote printer that shares a Windows print server: 

0x000006e4 (RPC_S_CANNOT_SUPPORT) 0x0000007c (ERROR_INVALID_LEVEL) 0x00000709 (ERROR_INVALID_PRINTER_NAME)

Affected parties However, the printer connection issues highlighted are specific to print servers. Therefore, printers specifically designed for home use are not affected by this challenge. Printers used in enterprises and organizations are the most affected by this issue.  The numerous printing problems can be traced back to the same update, however, they have been addressed with the subsequent patch releases that have been made. The KB5006670 update also affects Windows 10 users, thus, subjecting them to the same issues. Microsoft is yet to come up with a plausible solution.  Have you faced any challenges with your printer after making the update? Let us know in the comment section below.
