I have a Domain Controller which had installed RSA SecurID software
Few months ago we switched from RSA SecurID to Gemalto smart cards. This DC was the last machine with RSA software installed
Yesterday I uninstalled "RSA Authentication Agent for Windows" (through Add/Remove Programs). After restart RSA login window disappeared, but now no one can log on to this machine - even domain administrator (which was always logging in using only password). Everytime we have error message "unable to logon because of account restriction".
The same error users receive when they want o to login to their machines. We have another DC which is working without any problem, so we switched users to it.

Now I want to access this machine and fix it but don't know how

• No one can login to this machine, even in safe mode
• All sharings are working correctly
• I (domain administrator) can connect from another machine to Registry (HKLM), Event Log, Group Policy (but not Local Policy)
• psexec is connecting without any problem but I cannot see i.e. Local Policy without GUI.

Can somone help me to find the reason of this error? Someting that I can do from command line (using psexec)?

I need to buy a new server destined for Navision 2009 database on SQL Server 2008.
Database is 50GB large and growing 10 GB a year.
I'm considering to create a cluster on 2 servers. Didn't decided yet whether SQL server cluster or Hyper-V cluster.
Both solutions require external SAN shared between those 2 servers.

I'm a little worried about SQL Server performance of SAN.
I already have IBM Storage but I'm using it only for backup.
Here you have HD Tach comparison of my local disc (which is currently handling SQL Server database) and this storage

Red is local disc.
Blue is SAN.
What I see is that local disc has better seek time, but SAN has better read/write speed.

So which is more important for large (>60GB) financial databases - seek time or read/write speed?

Will Hyper-V kill my SQL Server performance?

Will more RAM help and balance seek time sacrifice?

• I have CA on the same server (windows 2003) as my second domain server.
• I created certificate for my user
• In Administrative Tools->Active Directory Users and Computers->(My user)->Account tab->Account Options I've checked "Smart card is required for interactive logon" check box

From that moment Windows required me to login using my smart card.

After few days I wanted to disable it.
So again In Administrative Tools->Active Directory Users and Computers->(My user)->Account tab->Account Options I've disabled "Smart card is required for interactive logon" check box

But windows completly ignores this setting. Even this domain server on which I disabled it still requires me to use smart card.

What else should I do to disable smart card logon ?

I have Vista Home Premium (x64) machine at home. I have www.google.pl set up as my default search engine in IE8.

Sometimes (since one month or so) when I search for something IE gives me "dns error" message and it cannot find www.goole.pl for 10-15 minutes. Frequency: 1-2 times/day. In the same time I checked google.pl on my PlayStation and it's working correctly Sometimes google.com and live.com is not working also.

I have router which I installed few years ago and didn't changed nothing in it since then, so I excluded it as a reason.

After short search on internet I found that nslookup is working without any problem, but ping is not.

When I've try ping -4 www.google.pl the problem dissapears until next time. This is why I think it's a problem with IPv6 and that somehow my Vista is using IPv6 even if it's not working.

I called my ISP but they claim that nothing was changed in their dns and I should search for a problem on my machine.

Yesterday my neighbour - which is using the same ISP - told me that he has the same problem with his Vista (x32), but thought it's google problem. When we talked he admitted that his machine with XP doesn't have any problems

So

• Is it problem with my machine or my ISP?
• If it's my machine - how can I find the reason and fix it?
• If it's my ISP - how can I prove it to them?
