refresh network connections script?

[neon]

I have a probelem on one random computer, its an admin machine, and I have set up permissions for the user to access resources on the ciriculum server. I have done this for many users and know that there should be no issue, however intermitantly the user loses the permissions and is requested to put the password in to no avail... after loggin off and back on it restores itself and is fine, just wondering if there was any script either .bat or .vbs that I could drop on the desktop to imitate a log off... ie refresh network connections? ive tried ipconfig /renew and it doesnt work... also tried net use * /delete /y and then remap and that doesnt work either...

 

Any help would be great...

try an .cmd file with "gpupdate/force" as the code. do test the code first, as that was just out the top of my head so could be wrong.

How about stopping and starting the DHCP client service?

 

net stop "DHCP Client"
net start "DHCP Client"
