Additionally, the services commonly used for worm propagation (RDP/TS, RPC, etc) are also used heavily for domain operations anyway. For many environments this would be one step forward, two steps back in terms of security.

If you are talking about a classic company network and dividing workstations into separate networks to prevent cross contamination, you have to consider the pivot points for most malware - email, file shares, etc, which can still allow malware to propagate between networks even if no traffic is allowed directly between them. Some kinds of malware, notably worms who propagate directly from one system to another via some kind of remotely exploitable vulnerability, would be contained by network segmentation, however those sorts of events are becoming increasingly rare (however when they do happen, they tend to be big events).

Hello All, I need few tips on Network Segregation to prevent spread of Malware. Can I avoid Malware spreading from one network segment to another just by segregating network with access list or firewalls?
