Network connection problem

Greetings,

For some while now, (since Windows 10 and all versions of Windows 11) I have have trouble with establishing a reliable bi-directional link between two Windows 11 (both are 25H2) PCs over gigabit ethernet.

When I open explorer on PC 1, I can 'see' the icon for PC 2 under "Network". When I click on the icon for PC2, the shared drives appear and files can be read or files transferred OK between PC 1 and 2. I can also map an network drive without a problem.

When I open an explorer window on PC2, I can 'see' the icon for PC 1 but when I click on it, all that happens is "Windows cannot access 'PC1'" I can ping PC1 ok but that is no surprise..

I have tried disabling Malwarebytes, etc, but to avail,.

Aaarrggh!

Some insight would be appreciated

Cheers

Steve

No guarantee but resetting the network on the laptop sometimes help. That fixed my Acer laptop with Windows 10 Pro when I couldn't connect to it anymore over my network.

Greetings, Mr Ed :-
Thank you for your suggestion... I have tried this before but the issue remains.. After enabling network sharing (selecting the private network option) I am still left with a normal function between PC1 > PC2 but not PC1 < PC2. What I have noticed is I DO get full functionality for a short while after switching on both PCs but soon after booting and, perhaps, logging on, the network issue returns.

Perhaps I need to see if Malwarebytes (or Windows defender is throwing a spanner into the works - though I am sure I have disabled them in the past.
