Thanks for the immediate response (happy easter btw!),
I've checked all adapters, reset ip and winsock with netsh, I have access to all network shares and the internet. But, I had problems installing a hp printer recently, also indicating that something is going wrong somewhere in my network. I think about upgrading another laptop with v2, but before that I have to deactivate the xp license, but that won't work because of the activation error after the update.
