DSN file stopped working!!

Hi Experts,
Our office moved to a new location and suddenly one of my pc's does not want to connect to SQL.
When I try to reconfigure the same DSN, I get the attached error.
Mysteriously, this is only happening to one pc.
Also I'm able to browse the server from that pc thru win explorer.
Any Idea?
FYI- I'm using SQL server login to connect.

It may be something to do with the domain controller and the registration of this particular PC with the domain controller. During your scheduled maintenance window, suggest working with the IT team to reboot the DC, the SQL Server and this workstation.

it seems the patching issue..

if the client is windows 7

 so please update the following patch..


if other  o/s run the windows update...  or update the lan drivers to latest..

all the best

Hi Experts,
It turned out to be the IT folks changed something on the network settings and as of now we must use the IP instead of the server name.
The reason why pc was acting differently is due to something set diff at the hosts file locally
Thanks .
