sen jag installerade xp pro ,,, ja!

Men detta skall vara ett ganska vanligt problem har jag hört!

Hittade detta som en lösning , men de e ju på engelska!!!

To disable this "feature" and restore your domain logons to their normal speed, open the MMC and add the group policy snap-in. Under Computer Configuration-->Administrative Templates-->System-->Logon, change "Always wait for the network at computer startup and logon" to ENABLED.
