I have the following problem:
My computer was working fine, suddenly after a reboot I lost Wireless Connections and LAN Network. I deleted the devices and recreated them, so I could navigate and work again.
I tried to do a System Restore and it warned me that I had no enought priviledges (I'm a domain admin)
When went to Event Viewer I couldn't access Security tab anymore prompting also that I had no enought permissions.
Launched secpol.msc Tried to edit the "Manage the secutity and audinting registries" and when I double click it, it is grayed and warns me:
"This configuration is not compatible with equipments that executes Windows 2000 SP1 or previous. Apply group policies objects, that contain this configuration, only to equipments that executes a more recent version of the OS".
Now this is weird as I have XP SP2...
I tried to do a VPN and now I only get:
Error 720: Unkown error after my user was correctly validated, this was on the TCP attempt to establish the connection. I know error 720 is well documented, however the warn for me is "Unkown Error" which is very strange. Tried to fix as a normal 720 but no success.
I installed the OS on another partition, was working fine like 24 hours and then exact same problem. I was poiniting to my AV Kaspersky however on this second installation there was no AV so it is discarded completely...right? The AV console is active and knows my PC...as same name was used.
Same thing has happened on 5 other computers at my work, here happens something more notorious:
When user tries to login Explorer crashes (this time not to me) and what we have to do is delete the user profile and recreate it and he can login again BUT same problems related to securiy persists.
I found this question on MS forum (in spanish) which has exactly the same sympthoms however this is dated on 2005! And he had an Intel application and no solution provided ever.
Now as this is part of a multiple problem and can't reproduce I only point to things all PC's have in common:
1. AV discarded as my PC last time didn't had nothing of it installed
2. Computers on domain, can be however if it was a policy I think ALL computers on my GPO or others were similar users also were affected will be done. I'm the only domain admin affected up to now. The rest of users were simple users.
3. Exchange Server...not sure it can damage the system in that way...
4. Brands, ok on PC but not on Laptops, mine is a Lenovo T61 and have also happened on a HP and a Dell.
On my event viewer I can't see nothing significant.
