Check your security and anti-virus setting and turn the firewall off.

check your pop-up blocker.  You might have msn and its related sites blocked.

I'm assuming you are talking about MSN Messenger here... you weren't very specific.  Messenger may be restricted or blocked on the PC you are for some reason.  If you are trying to connect through a firewall or proxy, it may be blocked and you need the firewall or proxy settings.  If it is not your computer, then the system administrator may have blocked access to your messenger.  You could probably try singing in using the web version of messenger (by going to the messenger web site).  Are you having the same problem with other messenger services (eg. AOL, Yahoo, Trillion, ICQ)?  Messenger services such as Trillion allow you to access other messenger services through one portal.  Otherwise you could try downloading and re-installing the messenger and see if that works.

You may need to upgrade to a newer version of Messenger. I had that problem too until I did. Or do I have the wrong idea of what your asking. You may need to close one of those before the window will come up (blocked?)

Figuring out why your computer can't get into secure sites is a tough one, but when it goes so far as to keeping you from logging in to messaging programs, it's a dilly of a pickle.  Here are some steps to take:\n\n(1) Visit http://www.windowsupdate.com/ (if possible, sometimes this sort of problem takes away this option) and make sure you have the latest and greatest.  Keep going back until it says you have no new critical updates.\n\n(2) Try another browser.  http://www.mozilla.com/ is where you can get Firefox.  Again, if you can't log into messaging programs, this might not work either, but it's good to have a backup browser anyway.\n\n(3) Check your date and time, including year and time zone.  Simple, yet it can cause this problem.\n\n(4) Disable ALL security programs.  Firewalls, pop-up blockers, browser toolbars, anti-virus....  This includes router firewalls---If you're going through a router, bypass it.  Keep them disabled for the duration of your troubleshooting.\n\n(5) Go to Start>Control Panel>Internet Options.  Clear the cookies, Clear the files, including "Offline" files.  Go to the security tab, click on "default."  Go to the privacy tab, click on "default."  Go to the connection tab, click on LAN settings, make sure there's no proxy (unless your ISP demands it to work---write it down if there's something there and removing it makes your internet stop working).  Go to the advanced tab, click on "restore defaults."  Click Apply, Click OK.  Try it again.  No dice?  Go back to Tools>internet options>advanced and scroll down to "allow third party browser extensions.  Uncheck it.  Apply>OK, try again.  If that doesn't work, go back in and re-enable third party browser extensions.  Apply>OK.\n\n6. Click on Start>Run and enter "CMD."  In the black box, type in "netsh winsock reset catalog"  When prompted, restart your computer.  Try again.\n\n7. Try a second, and even third spyware removal tool.  The Yahoo toolbar uses Pest Patrol which is pretty good.  You can get Spybot S&D and Ad-Aware at http://www.download.com/\n\n8. Do a System Restore.  Start>All Programs>Accessories>System Tools>System Restore.  Go back to a date where you know it worked.\n\n9. Nothing left that I can think of besides repairing or reinstalling XP.  If you've gotten this far, either you have/had a wicked piece of spyware that attached itself pretty good to something in your registry, or something just got corrupt in Windows.\n\nI don't think I've left anything out.  Best of luck to you!

Make sure u have a .NET account. U need that in order to use Windows messenger. The way of using it, is the same as other messenger. Put in your .net id and your password. Then connect.

What is the error message you are facing?  Please be more specific about your issue.  Are you not able to connect?  Ensure that you don't have a firewall like ZoneAlarm that is blocking Yahoo Messenger.  You can also select to connect without any proxies or Firewaal.  Go to Messenger > Preferences > Connection > Select the No proxies option.  I hope that helps.

Ok if you have a ROUTER and DSL MODEM then make sure you do not have any software firewall installed or you have problems.\n\nIf you have a Router you don't need software firewall like zonealarm or mcafee firewall etc..\n\nIf however you do not have a router go to the next step.\n\nSTEP 2.\nGo to Control Panel and then click WINDOWS FIREWALL and make sure it's enabled but click the EXCEPTIONS TAB.  If you see yahoo messenger or winamp in there delete them or uncheck the box.\n\nNow what will happen is the next time you start Yahoo messenger for example WINDOWS will ask you if you want to allow it.  SAY YES this time.\n\nSometimes people get the message and they say NO and then it blocks you from using that software over the Internet.\n\nSometimes Yahoo messenger has problems at the start up of your Internet.  Like when you reboot your computer at the beginning it will say it can't connect.  This is yahoos problem they have to fix and it happens to me and everybody.  It's not your computer at all.\n\nGo to the site below to have a more enjoyable experience with your computer

It may not be a firewall problem.Try unticking the "use proxy server box" and tick on the "automatically detect settings box" (in Tools/Internet Options/Connections-Lan Settings). It worked for me.

Try 1st off uninstalling and re-installing the Active Sync program. IF you have WM5.0, make sure you have activesync 4.0 or higher.   \n- Next, make sure your computer is up-to-date with microsoft updates, your firewall is configured correctly for the following programs to access the computer/internet: \nWcesmgr.exe\nWcescomm.exe\nRapimgr.exe\nCeappmgr.exe\n\nAnd configured to use the following ports: \n990\n999\n5678\n5679\n5721\n26675\n\nFor more info you can go to the link below for more assistance.  Hope this all helps and good luck.

Manage your add ons in your firewall. They are probably blocked.

There could be many things causing this problem. Make sure your regional settings are right. If all the settings are right then uninstall your messenger and install it again. Spyware and adware could also be blocking you log ons. If spyware or adware is present, then format the computer and try re-installing the messenger. A slow internet connection may also be causing this problem. You might also want to try a new account and see if that works.

Configure it within 1) your windows firewall or 2) your virsus/firewall protection software. Basically, you have have to add it or enable it as an exception or else removing it from the non-permit list.

try setting the connection preferences -> firewall with no proxies\n\n(you can do this when signing in - by clicking up on the left on the Messenger button, or after you've signed in in the same way, except you'll go like that: Messenger-> Preferences-> Connection)\n\nhope it works! it worked for me! ;)
