DNS/DHCP/IPCONFIG Problem

[sgscit]

huloo folks,

My internet connection keeps dropping out at work and as I'm the administrator I need to find out what is happening.

I have found that the following occurs:
Internet drops out
cannot ping past firewall.
IP addresses are not affected, ie ipconfig /all shows normal DHCP connection.
Some shares are unable to be contacted (all PC's and servrs are on the same subnet)
IPconfig /renew usually fixes issue.
Sometimes have to do a /release /renew
If this does not work, a /flushdns fixes issue for a while.

I'm sure this is a network issue and not a local issue as multiple PC's are affected (ie pretty much all of those that access the web)
I have created a batch file that renews the IP address and then opens IE, but this is only a bandaid not a fix.

appreciation expressed prior to assistance.

Cheers,

Pete

Can you ping your gateway ok when the connection drops?

TechFlunky,

I'm waiting on the next drop out. Shouldn't have to wait too long.

Glen,

lease time is 3 days.

Cheers,

My connection at home using a cable/modem is goofy also. About one out of three times I start the pc, there software doesn't find my nic. Made a batch file, release, renew, works everytime. Maybe put a batch file in users profile on AD so when they log on, it runs. Any error messages in the log files? Glen A. Johnson
