Can no longer mount iDisk with WebDAV

Question

Since last night I can no longer sync my iDisk, or mount any iDisk form other users. I've read the support answer that if you get "Last sync failed" with the iDisk sync, you should run "fix permissions" and reboot.
http://docs.info.apple.com/article.html?artnum=303032
However, this has not helped me. I've tried this several times. This problem is specific to my intel MacBook.
- iDisk mounting and syncing works just fine with my .Mac account on another computer.
- I tried mounting an iDisk on another user account on this MacBook, but this didn't work either. I suspect this is a system wide thing.
- I checked the permissions of "webdav_fs.kext" on my MacBook and my text top system, and they are identical. The desktop works still, my MacBook doesn't.
- I also checked that this kernel extension is loaded, and the system says yes.
- if I try to mount someone elses public iDisk folder, I get the following error message in the console:
Mar 28 20:27:40 Dr-Schaubs-MacBook webdavd[705]: (SCDynamicStoreNotifyFileDescriptor(gProxyStore, 0, storenotifyfd)) failed; going to SCDynamicStoreNotifyFileDescriptor; file: mount.tproj/webdav_network.c; line: 741
ANY help here would be greatly appreciated. I've tried all I could think of.
thanks,

Ok, I tries using the command line mount_webdav command. It didn't seem to work. I got no error messages, but no volumes were mounted.
I tried connecting to another (non-iDisk) web folder at bingodisk.com. This worked fine on my desktop, it doesn't work on the MacBook. This seems to confirm that this is a basic Finder webdav issue, not iDisk specific.
I looked through the system preferences to try to find any appropriate *.plist files to remove/reset. I tried removing
/Library/Prefernences/Network/com.apple.DotMacNotifications.plist
/Library/Prefernences/com.apple.networkConfig.plist
but this didn't do anything. Any ideas on what setting file might influence the Finder's webdav functionality?
If I try to do a iDisk sync in the Finder, the console give me the same message as when I tried to directly mount another person's public iDisk

I wonder which file it is trying to access here and failing??
