Connectivity issues on Windows 2003 Domain
Posted on 2008-06-17
Windows 2003 R2 domain and we've just added a 10 new pc's to the domain. We're running a SQL database off the server with application local on desktops. All XP SP2 desktops, they all log onto the domain using same generic login.
A couple of weeks ago, just after the pc's were added and some new cabling was installed, the app. connected to sql database started to show blank pages. It's only happening on a few of the new installed PC's and if you log out of the app and log back in, it's OK. There's another SQL app runs without error and Sophos.
The people who support the app say it's a networking issue.
They say a micro network drop out would not have a huge impact on the functionality of database and checking is done at Windows file sharing level. However if the connection to the server was lost for a millisecond and reestablished at Windows level, the application would not automatically refresh the links and have to be restarted. Stabilize your network this is not our issue.
I had some issues with the cabling and got the guys to re-check, they say it's OK.
The network is served by a really old 3com switch, all the rest of the hardware is new.
