Hi, we have a small business with 3 PC's (All Win-7) on a local network.

Yesterday, after a restart, one of the PC's could no longer be accessed by the others. It still appears in the Network list but any attempt to connect results in a "Windows cannot access \\OFFICE-PC" alert. This includes error code 0x80070035 "the network path cannot be found."

- The offending PC has full access to the internet/network

- The offending PC can connect to the other two PC's ok

- The offending PC network path is confirmed as \\OFFICE-PC

- I have used different network cables and ports on the switch

Any ideas from those with more knowledge than me? (not a high bar )

thanks

Try uninstalling those patches.

Thank you so much guys. This was indeed the problem - I uninstalled those updates and all good again.

Cheers!

Could this be the same problem for Windows 10. I've been having trouble lately, when awaking from sleep it won't reconnect the network shares and I often will have to enter a password etc which I'd rather not have to do.

Just a bit of a clarification on this:

https://support.microsoft.com/en-us/help/4487345/update-for-windows-7-sp1-and-windows-server-2008-r2

When the update is intsalled on a Win7, Server 2008r2 machine, it affects users conectting to network shares with local Administrator credentials for the PC that is serving the shares.

If you can use non admin creds that should resolve the issue without uninstalling the update.

Good practice says you should not be using admin creds anyway, but I've found three or four clients were I have done this, probably in a rush :)
