How to Choose a Workgroup or Domain Name
Ensure your workgroups or domains are named appropriately according to the following rules:
Ensure each workgroup and domain name is no longer than 15 characters. Ensure no workgroup or domain name contains spaces. Windows ME and earlier versions of Windows do not support workgroups or domains with spaces in the name. Whenever possible, ensure all computers on the LAN use the same workgroup or domain name. Using common workgroups and domains makes it easier to browse the network and avoids security complications when sharing files.
Ensure the name of the workgroup or domain is different from the name of any computer on the network. Avoid special characters in workgroup and domain names. Do not use these characters when naming Windows workgroups and domains: / \ * , . " @ : ? < > | For simplicity, avoid using lower-case letters in workgroup or domain names. The workgroup name doesn’t need to match the network name (SSID) on a Wi-Fi LAN.
