i spent like 3 hours last nice after pretty hot practice to try to figure out how to fix the cathy shack's dsl. tech support was pretty helpless, but it turned out to be a problem that had to do with the computer and not the dsl service. the culprit - a busted tcp/ip stack. i found the below info really helpful:

How to Recover from Winsock2 corruption:
==================================
Reinstall of the TCP/IP protocol to restore Winsock functionality
Step 1: Delete registry keys
A) Open Regedit from the Run line
B) Go to both of the following keys, export each of them, and then delete them:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock2
C) Restart the computer
NOTE: It is important to restart the computer after deleting the Winsock keys.
Doing so causes the XP operating system to recreate shell entries for those two
keys. If this is not done, the next step does not work correctly.
Step 2: Install TCP/IP on top of itself
A) Open the properties window of the network connection
B) Click Install
C) Click Protocol, then Add
D) Click Have Disk
E) Type the path to the nettcpip.inf file, for example: c:\windows\inf, and click
OK (if you try to click Browse, then browse to the \inf folder, it may not show up
in the list).
F) You should now see "Internet Protocol (TCP/IP)" in the list of available
protocols. Select it and click OK.
G) Restart the computer
When the computer reboots you will have functional Winsock keys.
NOTE: If the network connection properties contained more than the following three
items: Client for Microsoft Networks, File and Printer Sharing for Microsoft
Networks, and TCP/IP, then the additional items may need to be removed in order to
restore browsing. If those items are needed they can be reinstalled. The reason
for removing them is due to those items placing entries into the Winsock keys and
those entries will no longer be there.
Side effects and possible problems:
This method will restore basic functionality to the Winsock keys, but is not a
complete rebuild. On a default install of Windows XP the registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Winsock2\ParametersProtocol_Cat
alog9\Catalog_Entries - will have 11 sub-keys. When applying this method, the
Catalog_Entries will only have three sub-keys. However, it works and there does
not appear to be any side effects. The missing entries relate back to the:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces
key.
Also, third-party proxy software or firewalls may need to be reinstalled.
