# Companyweb, slow startup connection...

Hi

My clients are set to use http://companyweb/ as the homepage for the browser, yet they are sometimes unable to connect.  At other times, the page can be slow to load.
After variable amounts of time following a failure to connect, everything works fine again.
If the client has failed to connect to the companyweb http://companyweb/, it can still use the internet and there are no problems with the network that I am aware of.

The network runs under SBS2003 with dinamic IPs (DHCP), so on the clients IP and DNS are automatically assigned.

Here the IP CONFIG/all:

From the server:

As suggested in other similar topic:
"Add a CNAME (alias) record to your server's DNS Forward lookup zone for companyweb pointing to dc.vocedipadrepio.local."

I am trying to do this but I keep getting the following error
error message "An alias (CNAME) record cannot be added to this DNS name.
The DNS name contains records that are incompatible with the CNAME record."

And I've modified the "host" file located at C:\WINDOWS\system32\drivers\etc from:

127.0.0.1       localhost

to:

127.0.0.1       localhost
192.168.40.231    companyweb

Is it correct?

But... the problem is still present: sometimes slow startup connection to companyweb.

How to solve the problem?

I've tried to do this but

Thanks

This bit is almost certainly the problem:

Connection-specific DNS Suffix  . :
Description . . . . . . . . . . . :  NIC Fast Ethernet PCI Realtek RTL8139 Family
Physical Address. . . . . . . . . : 06-Q2-VF-YT-QA-V4
DHCP Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 10.0.0.100
Subnet Mask . . . . . . . . . . . : 255.0.0.0
Default Gateway.................: 10.0.0.1
Server DNS.........................: 217.72.96.66
194.183.2.129

You should not list *any* other DNS servers on your SBS system except for the Internal one - it will play havoc with authentication on the server itself (which the webpage will be using). You don't need any other DNS Server addresses and if you really want to use those they should be entered into the Forwarders Tab in your DNS Server by opening the DNS mmc, and opening the Properties for the server itself, you really don't need them there at all though.

It sounds like when IE is searching for automatic detection settings perhaps and pausing when it can't find the autodiscovery server, possibly due to DNS issues as above.  Try turning off proxy autodiscovery under Tools | Internet Options | Connections | Lan settings (or thereabout depending upon IE version).
