What you’re seeing
- Adding a network printer shows 'Windows cannot connect to the printer. Operation failed with error 0x0000011b'.
- Printers shared from a Windows PC or server stopped working for everyone right after monthly updates.
- Existing printer connections fail to print, and re-adding them produces the same error.
- Printers connected directly by IP address still work, while shared ones don't.
Common causes
Every environment is different, but these are the causes our engineers find most often:
- Windows security updates now enforce a higher authentication level for remote printing connections, closing a vulnerability in the print system.
- The print server and client computers are at different update levels, so one side expects stronger authentication than the other offers.
- A temporary compatibility workaround stopped having any effect once Microsoft moved to full enforcement.
- The printer is shared from an ordinary Windows PC rather than a properly configured print server.
- A non-Windows or older print sharing system can't meet the newer authentication requirement.
Why it matters
Shared printers are common in small offices precisely because they're simple, so when the sharing breaks, nobody can print invoices, labels, checks or reports. The tempting shortcut is to uninstall security updates or weaken protections, which reopens print system vulnerabilities that were actively exploited. Restoring printing in a way that stays compatible with future updates avoids repeating the outage every Patch Tuesday.

The engineer resolves the root cause and confirms with you that it’s working. You don’t just get a workaround, and you get a plain-English summary of what was wrong.
Pay only when it’s resolved
Fixed price from $99, invoiced only after you approve the fix. If it isn’t resolved, you don’t pay.
Frequently asked questions
Should we uninstall the Windows update to make printing work?
We don't recommend it. Those updates fix serious print system vulnerabilities, and the next round of updates would likely bring the same error back anyway.
Does every computer in the office need attention?
Not always. Depending on how printers are shared, the fix may center on the print server, the clients, or both, and the engineer confirms which before making changes.
