Windows 2008 Failover cluster. Printer driver was not installed. Access is denied.

Hello everybody

We have a "clustered" printserver in a two-node Failover Cluster (Windows 2008), and after the installation of SP2 (thats the change I can think of), i'm not able to install new printers (or remove) from another server's or pc's than the server that hosts the printserver for the moment.

I have tried from a Vista, the other cluster node and so on.. 

I have tried installing the printer from \\"printserver"\printers and from the printer console but only succeed if I do it from the "hosting" server
and it doesnt matter what kind of driver I use, always the same result.

(We have 162 printers with 71 drivers that already are installed the way that doesnt work anymore?)

It's realy important that it is possibly configure printers from other location than the console of the server, because its a hosted solution and not possibly to give the printeradministrator access to the console.

(I have tried with the firewall shutdown but with no luck)

any ideas??
