Computer just stopped communicating with server to get and report WU's. Any ideas on how to fix?

Things I know and have done:
.have 3 operating computers that perform Einstein WU's - only 1 does not work;
.Have no problem communicating with other internet servers with this computer;
.Error message states - Internet OK - project server may be temporarily down;
.When receive this msg, other computers are communicating with server concurrently;
.Have uninstalled and reinstalled BOINC - No change;
.Have checked preference settings on server and on local computer - did not find a problem - gave own setting "SCHOOL" - no change;
.This problem has been occurring for about 2 weeks - restarting computer did not help;
.Have not found a similar problem on this message board.

Thanks for your help!!!

What does it say when you go

What does it say when you go BOINC Manager->Advanced view->Projects tab->Select Einstein->on the left in the Commands column, is there a button showing "Allow New Tasks", or "No New Tasks"?
If "Allow New Tasks", click it. The button will change to "No New Tasks". This button shows what the option is, not the state it is in. When set to No New Tasks, BOINC will not request any work from this project.
Also, check that there's no "Resume" button, but a "Suspend" button instead. This button also shows the option, not the state it is in. When set to Suspend, BOINC will not request any work from this project.

Although in both cases the Status column in the Projects tab will show if it's set to No New Tasks, or Suspended.

Resetting the project won't help. This will only throw away work still in cache, and any science applications it had.
Uninstalling & reinstalling BOINC won't help either, as that leaves the data directory intact, in which there's the client_state.xml file, which stores these states.

Is there any chance that your firewall or AV in that host is interfering with the comunication with Einstein?

Thanks for your rapid

Thanks for your rapid response - regarding BOINC Manager Command Status - Have checked and the status's are the same as the computers that are working and the event log reports shows status change when altered. Log shows both new tasks and computer available for work are permitted - still no communications.

Regarding my Firewall

Regarding my Firewall precluding Einstein Communication - comfortable this is not the problem. Good idea - checked the settings - they are as set and the same as my other computers.

Thanks for the suggestion.

Are all three hosts at the

Are all three hosts at the same physical location ie. within the same subnet ?

Cheers, Mike.

If the 3 hosts are in the

If the 3 hosts are in the same network and using the same ISP then this could be a "poisonning" or error in the DNS cache of that host (more info here)... that can be fixed by opening a command prompt and running the following command: ipconfig /flushdns
(In windows Vista is needed to open the command prompt by right clicking it and choosing "Run as administrator" or it will give you an error saying that "elevation is necessary", IIRC this extra step is not needed on Win 7)

If the host is conected to internet through other ISP, may be there is an issue with that ISP... It happened before for other users where there was nothing wrong and they were not able to contact the servers only for a certain project and when using another conection everything worked...

By the way, try also to restart (or reboot) the router, sometimes a power glitch may put them in a weird status and they do weird things out of logic...

Beat me to it Horacio!

Beat me to it Horacio! :-)

Also, depending upon what network hardware you have ( I have a combined DSL modem, DNS server, DHCP server, VOIP, analogue phone splitter, wired router, wireless router and home pizza delivery service in the one device ) then possibly there may be a difference in it's handling of that host. Typically, using a browser say, try an IP address of 10.1.1.1 and that 'ought' get you the setup/config screen of that device. If so, check/compare the settings.

Cheers, Mike.

Another thing what perhaps

Another thing what perhaps can help is to be sure that nothing is changed in the hosts file.
In the early time of the internet before DNS (Domain Name System) exists the hostnames were resolved with the hostsfile and this actually exists but on most systems it isn´t needed anymore.
But there are existing Viruses that can change for example that file and your system can´t acces to your virus protection update server or to the internet.
you can find that file in system32\drivers\etc\hosts
and open it with editor or something like this

If it looks like this all should be ok there

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host

# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
