Can't see 1 PC on the network

I currently have 3 PCs on a network which has been set up for a number of years but now 1 of the PCs can't see 1 of the others. Typically this is the 1 PC it does need to see as this is where the company file is stored. The PC that it can't see can see that one so it is only a one way thing. This will maybe make it clearer.

PC 1 can see PC1, PC2, PC3
PC 2 can see PC1, PC2, PC3
PC 3 can see PC1, PC3

Any ideas what could be causing this change and how it can be rectified?

see if the above threads can help

 

Thanks for getting back to me so quickly.

I've had a look at both links and, although I was sure it wouldn't be any of these as the PC I can't access from 1 PC I can from another rules out all the usual checks I did them and all is indeed ok and set up as it should be.

I just find it very strange that this set up has been in place for a number of years and has gone through various PC and printer changes, computer upgrades and antivirus/firewall changes and it has always functioned well until this last week or so...

above is another link to try, I am not too knowledgeable about home networks, but anytime a pc is doing something other than what you told it, that generally appears to be malware,

have you run some scans??

did you install a program on pc3, that you did not install on the others??

Hi,

I must apologise for not getting back to you. Although the PC3 still couldn't see PC2 it was able to access the company file again so had forgotten all about the 'problem'.

It's back again though and can't access the company file from PC3.

I'll have a look at the links and also malware scans and let you know how I get on.

 

okay will check back, please keep track of what happens, and when so we can further troubleshoot.
