Key notes

  • Users have needed to fix 0x0000007c (ERROR_INVALID_LEVEL) and 0x000006e4 (RPC_S_CANNOT_SUPPORT) errors in Windows 11 because of a patch update.
  • Updating Windows 11 will likely resolve the 0x0000007c error, but following the other solutions will help as well.
  • Some users might need to restart certain printer services to resolve the 0x0000007c (ERROR_INVALID_LEVEL) error.

0x0000007c (ERROR_INVALID_LEVEL) is a printer error more users have encountered since November 2021. That error arises for some users when they try connecting to shared remote printers on networks. When that issue occurs, this error message pops up:

Windows cannot connect to the printer. Operation failed with error 0x0000007c.

Consequently, users can’t connect to remote print servers. As this is more of a print server issue, it has had a more notable impact on enterprises and organizations than home users.

The 0x000006e4 (RPC_S_CANNOT_SUPPORT) error is also a very closely connected one. Although it has a different error code, that’s much the same issue as 0x0000007c. When that error occurs, users can’t utilize network printing.

What causes the 0x0000007c and 0x000006e4 errors?

Microsoft released a Windows 11 KB5006674 patch update in October and November 2021. That update has triggered the 0x0000007c and 0x000006e4 networking printing issues for users. The KB5006674 update page states:

After installing this update, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:


Thus, the KB5006674 update is a confirmed cause for the aforementioned network printer errors on Windows 11. If you need to fix the 0x0000007c and 0x000006e4 errors in Windows 11, your PC might have received the KB5006674 update.

However, the 0x0000007c and 0x000006e4 errors did exist before Microsoft released buggy updates. Those errors can occur because of corrupted printer drivers, Print Spooler service glitches, or other standard printer inconsistencies.
