Make sure you used the fully qualified name as the target for your CNAME - putting in an IP address will not work....
-Brian -----Original Message----- From: McGovern, Michael [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 06, 2008 6:15 AM To: NT System Admin Issues Subject: Setting up a CNAME in DNS I followed the simple instructions How to Add a CNAME A CNAME (or "Canonical Name") is an alias or an additional host name that is resolved to the IP address of an existing host computer in the DNS namespace. For example, if you use the same computer as both a Web server and an FTP server, you may want to resolve both the WWW host name and the FTP host name to the same IP address. Using a CNAME, you can resolve both names to the same IP address. To create a CNAME: 1.Start the DNS snap-in. 2.Click the DNS Server object for your server in the left pane of the console, and then expand the server object to ex pand the tree. 3.Expand Forward Lookup Zones. 4.Under Forward Lookup Zones, right-click the zone that you want (for example, example.com), and then click New Alias (CNAME). 5.In the Alias name box, type the alias that you want. For example, type ftp. 6.In the Fully qualified name (FQDN) for target host box, type the fully qualified host name of the host computer that you want. For example, type www.example.com, and then click OK. Once I created the cname of ctcvcweb which I called imaging I waited for it to propragate in my AD environment. I should be able to ping both the real name and the alias correct? The alias still is not working, am I missing something?\ C:\>ping ctcvcweb Pinging ctcvcweb.corp.cambridgetrust.com [10.176.69.219] with 32 bytes of data: Reply from 10.176.69.219: bytes=32 time<1ms TTL=127 Reply from 10.176.69.219: bytes=32 time<1ms TTL=127 Reply from 10.176.69.219: bytes=32 time <1ms TTL=127 Reply from 10.176.69.219: bytes=32 time<1ms TTL=127 Ping statistics for 10.176.69.219: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms C:\>ping imaging Ping request could not find host imaging.
