While working on a connection problem, I checked my DNS cache this is what I found.
For the record I don't do adult sites.

Error: unrecongnized or incomplete command line.

/flushdns | /displaydns | /registerdns |
/showclassid adapter |
/setclassid adapter [classid] ]

where
adapter Connection name
(wildcard characters * and ? allowed, see examples)

Options:

/all Display full configuration information.
/release Release the IP address for the specified adapter.
/renew Renew the IP address for the specified adapter.
/flushdns Purges the DNS Resolver cache.
/registerdns Refreshes all DHCP leases and re-registers DNS names
/displaydns Display the contents of the DNS Resolver Cache.
/showclassid Displays all the dhcp class IDs allowed for adapter.
/setclassid Modifies the dhcp class id.

The default is to display only the IP address, subnet mask and
default gateway for each adapter bound to TCP/IP.

For Release and Renew, if no adapter name is specified, then the IP address
leases for all adapters bound to TCP/IP will be released or renewed.

For Setclassid, if no ClassId is specified, then the ClassId is removed.

Examples:
> ipconfig ... Show information.
> ipconfig /all ... Show detailed information
> ipconfig /renew ... renew all adapters
> ipconfig /renew EL* ... renew any connection that has its
name starting with EL
> ipconfig /release *Con* ... release all matching connections,
eg. "Local Area Connection 1" or
"Local Area Connection 2"

some additional info

Sorry I am late getting back on this havent been able to get online. Connection unable to establish a gateway and resolve dns. Kinda why I looked at my cache LOL.

I checked my hosts file I have about 300 entries in there, Iuse Spybots and hupguru's list.
Only a couple of the dns cache dump are in the hosts list.
I have checked the line from the house to the pole and the computer shows no problem. The icon shows the connection to be established with no problems reported by windows. Yet the modem wont stay lit up and It can't establish a gateway or connect but now and then.

Called RR but they show no problems am trying to get them to give me another modem. I also have tried 3 different nicks to no avail

You need to go into you NIC properties and enable "Obtain IP automaticly"
And "Obtain DNS automaticly".
Are you trying to run a static IP?

I have the nic configured to obtain IP and DNS automatically.
No this comp is not on a static IP.

Thanks for the suggestions tho. I am leaning towards a failing modem it is 4 yrs old after all LOL.

Itried 3 different nic's and 2 other computers. All have had the same problem. Connection is lost intermittantly and it then can't establish a gateway or resolve DNS altho the icon posts a message it is connected and windows reports no problem with the connection.

It could be something as simple as bad POTS (Plain Old Telephone Service) wiring. Father-in-law had a problem with his wire. We jumped it to the POTS service box and wired it straight and it resolved the problem. The teleco came out and ran new service from the street to the service box, replaced the service box, and to his DSL modem.
