ActiveSync 4.2 and 4.5 not seeing device...

---

Ran into a problem. My ActiveSync wouldn't recognize my device. It's showing up within Device Manager but when I connect it no go.

ActiveSync knows something is being connected because it starts to do it's thing but then errors out and cannot establish a connection with my Athena.

Anyone else run into this problem?

I've uninstalled/reinstalled ActiveSync 4.2 AND 4.5. Checked to ensure that the services that ActiveSync depends on are running, etc.

Any help would be greatly appreciated.

you are not running Windows Vista are you?

No. Running Windows XP Pro.

It was working a bit flakey at first. I had an HTC TyTN synching perfectly on ActiveSync 4.5. When I got my Advantage in, I hooked it up and it acted a bit weird but trying to hurry and get my phone up and running I avoided setting up the relationship so it was a "guest". I installed software onto my Advantage without a problem. Later, once I got my stuff migrated from TyTn to Advantage, I deleted all existing relationships in ActiveSync then tried to join the Advantage to it and it knows the phone is there but won't establish a profile with it. Did a repair on 4.5, didn't work. Uninstalled/reinstalled 4.5, didn't work. Uninstalled 4.5 and installed 4.2 (the version on the CD), didn't work. Researched ActiveSync and noticed that one of the dependent services was stopped...I activated this service, rebooted...didn't work. ActiveSync uses a TCP/IP port to listen on so I did "telnet 127.0.0.1 xxxx" where xxxx is the port and it's there listening, so requests can be accepted.

I'll probably try hard resetting my device this weekend if no one has any recommendations. Once I find the answer I'll post it here.

Possible causes are:
- Corrupt ActiveSync on laptop. An uninstall/reinstall should have resolved this unless the unlerlying OS files that ActiveSync utilizes are corrupt and those weren't repaired/replaced during the reinstall.
- Corrupt ActiveSync on phone. Can't be uninstalled/reinstalled to my knowledge without a hard reset so not much I can do.
- Maybe the GPRS monitor I installed caused a problem. I initially installed the one that came on the CD but had to remove it because it kept locking up the phone and slowing things down significantly.

Are you running BitDefender as your AV/Firewall? A recent update prevents ActiveSync from working correctly. see link:

No. Not running either. I did a hard reset and it started working again. Then a few days later the same thing happened again. Not sure exactly what the problem is but since I already did a hard reset and the problem resurfaced, I'm going to have to do some debugging to figure out what the culprit is. Just hate wasting time going through a debug. :-/

Hi,

I am experiencing similar problems with my T-Mobile MDA Compact 3.

I recently re-installed my PC and installed 4.5 having previously used 4.2.

After a few days it stopped syncing. It still allowed you to view files on the phone from the PC and install programs, it just would not Sync.

I did a hard reset of the phone to night and it worked fine to begin with but now it appears to have stopped working again.

Does anyone have any ideas what is wrong. I am assuming that AS 4.5 is the problem here.

Regards

That is weird. After my initial hard reset, it happened again. I did another hard reset anyhow because I was trying out new programs and wanted it to be clean again. Not sure what was causing mine to stop functioning but when it did, I couldn't connect to the phone at all. I wouldn't browse nor synch, etc.

It has now definately stopped working.

Looks like I will have to hard reset the MDAC3 again and try from scratch using AS 4.2.

My only concern that without reinstalling my PC there may be some residual problem in the registry or elsewhere that the new installs are picking up.

I am about to try another trawl of the Internet to see if anyone else is experiencing these problems, and has a solution.

Hi,

....and we are back. I went back to Microsofts site and looked over all the various solutions for AS problems where you are connected but not syncing.

There is a suggestion that USB hubs can cause problems and that you should connect your phone directly to the PCs main USB ports. I had discounted that as it has always been connected to the USB port with no problems.

I have just tried it and it and it is now syncing fine again.

I am assuming that AS 4.2 coped with the hub okay or my reinstall of the PC had caused the problem.

I will now try some soft resets and re-boots of my PC to see if AS keeps working. Fingers crossed!!!

...and now we are back to square one.

I also tried unistalling Outlook 2007 and reinstalling 2002 and AS 4.2 but it did not even connect.

One thing I have also noticed is when you run the troubleshooter in AS it seems to think that their is not a copy of Outlook as it tells you to install Outlook 2000 or higher. This would explain the lack of syncing while the device appears connected in terms of being to explore it and install programs.

Tried a search on this on the Internet but did not find anything.

Looks like a full reinstall of the PC and a Hard Reset of the device is required.

Deep Joy, thanks Microsoft.
