Network User Login and Authentication

Task Objective:
Correct problem of slow authentication and users not being able to login the network.

Solution:
Redesigned the server infrastructure by reorganizing where the services were deployed within the network. Re-deployed WINS, DNS, and Domain Controllers to reduce replication traffic across slow WAN links. This increased performance and reduced login times. We then placed sniffer software throughout the network to perform packet captures. We discovered that there were several unneeded protocols on the wire. We developed scripts to run on the sniffers to export the IP addresses of the computers utilizing the offending protocols. Login scripts were then modified to remove the protocol entries from the registries. This resolved the slow logins.
