Server loses internet connection
in [Windows Servers]
|
From: Zebby on 26 Jan 2010 04:48 We have a server (Windows Server 2003 Ent R2) that keeps losing it's internet connection. This is a problem as this server needs a constant connection for continious off site backups. It can go off for up to 25 minutes at a time and if left alone it will eventually restore itself it seems. It looks like running ipconfig /registerdns will fix it. Server uses a static IP and is set up correctly. It has 2 NICS teamed using the HP management software. When the machine loses its internet connectivity it can still ping/access other nmachines and still works in every other respect - it is running SQL server and other machines have no problem accessing it. Machine has had a reboot. Any thoughts?

You cannot have it both ways. Either your machine has lost Internet Protocol connectivity, in which case it will be inaccessible and ping won't work, or ping works and other machines can connect, in which case your machine has not lost IP connectivity. Describe your problem properly.

Expand on what you mean by "internet connectivity"; just your backup site? Or all internet connectivity. Are other computers still able to access that/those site(s), at the same time that the server cannot?
From: Zebby on 26 Jan 2010 10:32 Yes to your first point, the server continues the work as normal in every respect. By 'internet connectivity' I mean I'm just getting page cannot be displayed on any website, not just the one we use to manage the backups. No other machine is affected.

Sounds like it may be a DNS configuration problem. Your DNS server(s) should be configured with *Forwarders* that point to your ISP DNS servers. DNS on your server should point to itself. Your DHCP should be configured to point your clients to your internal DNS server for DNS. Take a look at this article, if you have not configured it that way. http://support.microsoft.com/kb/323380 "Zebby" <someone(a)nowhere> wrote in message news:udBM$ypnKHA.5552(a)TK2MSFTNGP05.phx.gbl... > Yes to your first point, the server continues the work as normal in every > respect. > > By 'internet connectivity' I mean I'm just getting page cannot be > displayed on any website, not just the one we use to manage the backups. > No other machine is affected. > > "JohnB" <jbrigan(a)yahoo.com> wrote in message > news:uNJEdXpnKHA.1548(a)TK2MSFTNGP04.phx.gbl... >> "Zebby" <someone(a)nowhere> wrote in message >> news:e%23OzpymnKHA.5344(a)TK2MSFTNGP04.phx.gbl... >>> When the machine loses its internet connectivity it can still >>> ping/access other nmachines and still works in every other respect - it >>> is running SQL server and other machines have no problem accessing it. >>> >> So it looses internet connectivity, but not LAN connectivity? >> Expand on what you mean by "internet connectivity"; just your backup >> site?
