Slow login in an active directory can be caused by the following wrong settings: 1. Auto-Negotiation First of all disable "auto-negotiation" for your network card(s). Set it to the highest level manageable by your network hardware, eg. 100mbit full duplex. This will increase the login speed a lot. 2. Reverse Lookup-zone Next you have to set up the reverse lookup zone for the DNS server properly. Be sure to add a reverse zone that matches your network. For example if you are using IP in the range 192.168.0.1 - 192.168.0.150 enter "192.168.0" for your reverse lookup zone. This will again speed up the login process. I hope this helped someone out there. Kind regards, Matthias

eliminating autonegociation is a two not one step process. Just setting your nic to a static setting of 100mb full duplex might not work. Cabling, EMF, distance, and equipment all make a difference. What causes auto not to work is the nic thinks its 100mb half duplex and the switch thinks its 100mb full duplex [or some variant of this mismatch]. This generates crc errors along with other tx/rx errors. This requires resends of the packets slowing the connection down even more. What will work is set both the managed switch port the nic is connected to and the nic to the same setting which in this case is 100mb full duplex. That's how you do it.
