I changed the permissions back, because the answer is WindowWasher. And to some extent TweakXP Pro(I use it to configure certain dislikes of winxp). I had to set the AlwaysConnectedWaitSeconds=120 for the problem to be solved. Now I have no errors. Thanks for the hint about the log file. I had not looked at it. It showed some interesting info about connections. That is what led me to TweakXP.
At any rate the answer is setting always connected. The Temp dir permisions were of no use except that I had granted to much rights.
