AH - HA! Thanks knreed.
That seems to be the Magic Spell. Forcing ntlm auth seems to have fixed the client - server interaction.

Now -- any ideas about why my Proxy settings are being overwritten by my computer name? It will not stay on the proxy url that I place in the setup area for proxy and port. Advanced -> Options -> HTTP Proxy

Hi Sekerob - Thanks for your help.

Ref: client version 5.10.45
Now that my BOINC client is talking with the server -- I would like to have my Proxy settings actually maintained between each execution of the BOINC client.

From the tool bar: Advanced -> Options -> HTTP Proxy
There are 4 pieces of information that I have entered:

HTTP Proxy Server Configuration
Address: blah1.blah2.com
Port: 80
User Name: smithbill
Password: *********

So, for me, when I execute the BOINC client - I must open this window and re-enter the Proxy Address and Port number every time I execute the client. Because -- instead of keeping the correct Proxy and Port number from the last time I entered the info --- I now have:
Address: BillSmith <--- this would be an example computer name.
Port: 0 <--- I'm not sure where this comes from.

The Username and Password seem to be OK as entered from before. I have somehow lost the real Proxy address and Port number.
So -- I end up having to re-enter that information every time I start up the client.
I believe that this means that my actual Proxy information is not there and my client will not be able to communicate with the Server.

I have examined the file called: client_state.xml
It contains the incorrect info. I can change it in the file to be the correct info... but, the next time the client is started -- the info reverts back to the wrong stuff. It seems that the client in not paying any attention to the:
<http_server_name>blah1.blah2.com</http_server_name>
<http_server_port>80</http_server_port>
information in the file. And it becomes overwritten at the next client startup.

Thanks for your help
