The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (Logon).
Posted on 2014-03-03
I have a client that is having terrible issues with logging onto his Domain Network. The title is what I get in the event manager and the time is currently taking about 3550 seconds, which is about an hour. Yes it does eventually logon and then all is well. This started to happen about the same time that I had installed GFI Remote Max management and then the AV that comes with it, so as it happened about this time, that is the initial route I went down, first removing it all, then removing all startup items in msconfig, I did a cleanup and it looked like the computer had never been done as I removed some 34Gb of files using the disk cleanup tool, then defragged, it was 25% fragmented, then run diskcheck and whilst he was home on the weekend, everything went good again. The minute he was back in the office today, it was the same again. Which is when I went onto the event logs and found this.
Our setup is a Windows Small Business server 2011 standard with sp1, 24GB RAM adn 2.4ghz Xeon processor. The client machine is Windows7 pro with 8Gb of RAM and he logs onto a domain as mentioned.
I did some digging around on the web about this error and there are lots, but all are pointing to issues relating to Server 2008. Some of what was mentioned, was to disable IPV6, disable TCPIP Chimney, but none of these have helped the situation. As soon as you login in safemode all is well. I even tried logging in with the administrator account as this is a different profile, but still nothing,
So now I am at my wits end having spent 6hrs on it.
Can someone please help
