I have windows SBS 2003 on a 30 user network. Throughout the day while trying to browse the web we often get "page cannot be found" message in IE (or any other broweser of choice). While I get this message I can ping the offending websites IP address but not it's Domain name. I can also ping anything within my LAN & even resolve local Names. after a minute or so I can refresh my broweser & the site will load. Also if I have a dialup connection setup up & have "dial whenever a connection is not present" selected in my internet properties, the dialup networking box will pop up as if I didn't have a connection. The problem occurs with any website & if browesing will probaly occur 1 out of every 5 Domains we try to get to. I currently have my SBS setup with only one NIC which is plugged into a HP switch which has a Linksys router plugged into it & then connected to cable modem. my SBS is acting as the DHCP server & I have the DNS on all my local machines set to my SBS's IP.

Does any one have an suggestions on how to resolve this problem.

I'd start with having the line checked for noise.

But, you may also be encountering a problem with DNSProbes settings.

Try running this script on your server and see if it resolves the issue.

Code:

' NAME: DNSProbes.vbs

'==========================================================================
on error resume next

Dim path

Set WSHShell = Wscript.CreateObject("WScript.Shell")

'set the key path here.  IF you don't end with a '\' then WSH assumes you are pathing to a value.
path = "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters\"

WSHShell.RegWrite path & "EnableDnsProbes","00000000","REG_DWORD"

If err then
	msgbox "Error Encountered"
else
	msgbox "DNSProbes Sucessful"
End if

I hope you find this post helpful. Please let me know if it was.

Try to change your dns settings. In active directory your first dns entry should be your DC that is running DNS. In DNS on the server you should setup DNS forwarders. Sounds like you are resolving off a bad DNS server or you have a bad router or firewall. Could also be your internet connection as well. I would go to workstation and put in a different static DNS entry. 4.2.2.2 is one you could use. Then try to ping by name and see what you get.

There should also be some diagnostic tools in your router or firewall that you could use to ping names.

It can be as simple a bad port on the hub that your gateway is plugged into.
