kinit cannot resolve network address

[Gwen Parker]

I'm trying to configure a Solaris 8 system to authenticate Samba against 
Windows 2003 ADS.  I've compiled the appropriate packages; however, I'm 
quickly stuck trying to get my kerberos ticket.   Here's the error:

sumac:/opt/local/kerberos5/bin# ./kinit admin at DCRI.DUKE.NET
kinit(v5): Cannot resolve network address for KDC in requested realm while 
getting initial credentials

Here's the lowdown:
Samba client -- sumac.dcri.duke.edu  152.16.48.61
ADS server - vmsodium.dcri.duke.net 10.0.101.65

My /etc/resolv.conf 

sumac:/opt/local/kerberos5/bin# more /etc/resolv.conf
domain dcri.duke.edu
nameserver 152.16.48.78
nameserver 152.16.49.44
nameserver 152.16.49.47

Although I rather not modify my /etc/resolv.conf, I've read that this 
error is due to DNS lookups.  I am able to resolve using nslookup.   I 
have tried 1) adding my ADS server's IP to /etc/resolv.conf and a "search 
dcri.duke.net" line.  I've also tried using the IP in the krb5.conf file. 
I can't get past that error.  Here is my /etc/krb5.conf.. 

[libdefaults]
        default_realm = dcri.duke.net


[realms]
        dcri.duke.net = {
#       kdc = vmsodium.dcri.duke.net
        kdc = 10.0.101.65
        }

[domain_realms]
        .kerberos.server = dcri.duke.net

Any help would be greatly appreciated.
