ActiveSync 4.5 Support Code 85020006 and 80072f7d


I just updated (in January 2008) my AT&T HTC 8525 phone's Windows Mobile 6 OS. Since then I was not able to sync with my host PC.

I get two errors:

Issue 1: Support Code:85020006
Issue 2: Support Code:80072f7d


Note that this involves registry changes so be careful with it.

Issue 1 can be fixed by;
  • Open ActiveSync
  • Choose File->Connection Settings...
  • Change "This computer is connected to" to The Internet
After you fix above issue, try the Sync and you may get the second error.

The second one is nastier and requires a registry hacking on your Windows XP PC (i.e., not the phone). I suggest that you save current registry settings before you do this.

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows CE Services]

This site has the registry file that you can double click and modify.

This disables the Layered Service Provider (LSP) that use the Windows TCP/IP stack. But by doing this, you are going to forfeit the support rights from Microsoft.

After doing above two things, all the issues were resolved for me.

Time Saved:

This can save you at least 1 hour of hunting. These are not described in Microsoft web sites clearly.

Sorry the first solution did not work. You may have other problems, so I wish you a good luck on that issue. Do not attempt the second solution unless you are through with the first one because you are likely to have another issue that I did not have.

Apparently the second issue, if you do it, MS won't support your PC/PPC, so please be aware. If necessary you need to back up your whole computer before changing it. Basically though, go to the site that is mentioned, and grab the .reg file, double click it and the changes will be made.

P.S.: The usual disclaimer. I won't be responsible if you broke your stuff due to my advise.
