a) Do you have AD integrated DNS? Or primary/secondary DNS zone files for the zone in question?
b) Using nslookup you can check with a particular DNS server to see what it currently thinks a particular name resolves to (if anything), just in case the DNS server you machine is using is not the DNS server you created the CNAME for c) Did you verify in DNS MMC Snapin that the CNAME is propagating? d) Pinging just a hostname (with no DNS suffix) relies on appropriate DNS suffixes being configured for your network adapter. Can you ping the entire FQDN (imaging.domain.whatever)? If so, the your DNS suffixes aren't correctly configured.

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.
