I have an Exchange Server 2003 Enterprise in a Windows 2003 Enterprise Edition Server. The server is a Dell PowerEdge 2950. I also have the Primary Domain COntroller in Windows Standard 2003 Server. I just bought a PowerEdge 1950 but I want to install Windows 2003 Enterprise Server 64 bit Edition. Are my servers or my network affected if I have one server with 32 bit operating system and another server running 64 bit operating system?

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
