Any user can't access shared folder from one computer

[acolade]

Hi everyone,
I have a specific problem. There are some shared folder on one server with access for everyone. But one folder is inaccessible from one specific computer (PC1). I have tested it with several users which have access right. Users can reach the folder from any other computer. Also other folders (with same access right) from PC1 are accessible.

Where can be a problem?

I have tried to remove the computer from domain and add it again.
There are no viruses detected.
I have tried to map the foldet to another drive letter. (The share is inaccessible with "\\computer\folder" too.)

Do you have any idea, where can be a problem?

Thank you and have a nice day.

Ok, but only one of these questions matters -> av: McAfee.

Anyway, I have already reinstalled the computer.
There were probably these problems:
1. Some service or program connects to the specified share during boot/logon and user uses credentials of the service to access the share. - Not confirmed.
2. There were some registry records / local access policies, that I did't found.
OR?
