I am having a problem each time I re-boot my XP PC. I get a message that the desktop cannot connect to client and do I want to retry. Each time what I have to do is go in and select compute as "localhost" and everything works fine until I re-boot.

I have checked and BOINC is allowed in Windows Defender and I have also added the whole BOINC folder to the allowed files.

Any ideas?

Which version of the Grid Republic BOINC is this?
Mind... the Grid Republic version is a third party BOINC with Account Manager included. Although I don't mind trying to help you, I still think your best bet is to email them at support at gridrepublic dot org

The only reason that I am using Grid Republic is because I thought that I might solve the problem that I am having by trying them?? No change though pre vs post Grid Republic

I don't know if this makes any differece but I have been using UD Agent for about 4 years on this machine without any problems, even forget that it was installed. But got a message that the UD was being phased out to BOINC so am trying to get it going with the same amount of intervention on my part as I had with the UD agent.

OK, so your general problem is that your BOINC Manager loses connection to the client? As you have thought of already, that's because something is blocking the communication between the client, the GUI (and the creen saver).

Either something has taken up TCP port 31416 in your system before BOINC starts up, or you haven't allowed all three components in the firewall or WD.

Which version of BOINC did you use before trying GR?

OK to make things a little easier I uninstalled Grid Republic and then re-installed BOINC my error message now says "BOINC Manager Unable to connect to client"

So after selecting "localhost" and everything now works OK (until the next time I re-boot) here is what my log says:

I notice in the log "12/14/2007 3:19:22 PM||Host location: none" Is this my problem? Why doesn't it say "localhost"?

This is the venue that the computer (local host) is in. Since local host can't be in local host, it doesn't show that. ;-)

Venues are work, school, home and --- (none). (none) is the default for many projects. They are used when you have more than 1 computer and you want to give them separate resource shares and general preferences (and you don't want to or can't use the advanced preferences in BOINC 5.10 or you use a pre-5.10 version of BOINC).

OK, stop BOINC please, navigate to your BOINC directory and delete the gui_rpc_auth.cfg file. Then restart BOINC and or (better) reboot the computer to see if that fixes things.

Done (Thanks! But unfortunatley no change; Problem persists

Back to the Windows Defender theory then. I don't have it, still using Windows 2000, so not being able to test it either. Isn't that an anti-spyware program though? Can you tell it to separately allow and boinc.exe and boincmgr.exe and boinc.scr?

Do you have a software firewall as well? Or is the Windows firewall on?
Did you allow all 3 in that?

FYI, Windows Firewall (at least the XP one) never caused me any problems with BOINC.

Aye Nick, but you're special. ;-)

OK it appears to be fixed. I re-attached to computer "localhost" and now it seems to work fine.
