One user on our network has a problem where IE pauses for about 20 seconds before loading web pages. When you type an address in and press enter, IE takes about 20 seconds before it starts loading the page. This is occurring on one Windows NT workstation (with SP6) machine regardless of who logs into it. Other users on the network are working fine.
We are on an ethernet LAN, connected to the internet by a relatively fast connection. Our proxy is MS ISA server.
The staff member has the correct proxy server settings.
I cleared his temporary internet files, history and cookies. His Temporary Internet File size was set to 10 MB. Autocomplete was turned off temporarily. Neither of these steps made any difference.
The problem occurs both in IE and in Netscape. I have reinstalled IE 5.5 (our current standard) and then IE 6.0 SP1 both of which made no difference. I looked at running processes on the PC and turned off anything non-essential. I temporarily disabled the anti virus scanning software and pared down the services to the bare minimum.
The problem is limited to sites on the internet - local sites seem to be fine. I checked the PCs' hosts file, which only has 3 entries. I tried connecting to an IP address of a website and the same thing occurred.
Any suggestions would be much appreciated.
