Re: Slow DSL Connection SBS2003

Hi Anthony,

Thanks for your update.

I am sorry for the delayed response due to weekend. Please understand that
the newsgroups are staffed weekdays by Microsoft Support professionals to
answer your systems and applications questions. Your understanding is
greatly appreciated!

Also I would like to apologize for misguide you. Since in SBS environment
the external NIC is also using the internal IP address as the DNS, if we
disable the internal NIC, it's expected that the DNS resolution cannot be
processed successfully. This is cause that the server box can not access
internet if we disable the internal NIC. Sorry again.

To trouble shoot the issue, let us check the following settings:

Please check if the connection limit has been set in the ISA server, if
yes, please disable the connection limit to see if the test result will be
improved. You can refer to the following steps:

Open ISA Management console, navigate to ''Configuration''\''General''. In
the middle panel, click ''Define Connection Limits'' link and UNcheck
''Limit the number of connections''. Click OK to close the dialog box and
click ''Apply'' button to enable the settings.

Then please test the issue again, what is the result?

I appreciate your time!

Have a nice day!

Sincerely,

Jenny Wu
