ScanMail cross certificate error

I configured a new Domino domain on an iSeries currently supporting 
another Domino domain and several existing partitions.  Some of them 
running Trend's scan mail.

I used the following commands:
CFGDOMSVR SERVER(OAKFARM01) 
          OPTION(*FIRST) 
          DTADIR('/Domino/OAKFARM01/Data') 
          ORG(OAKFARMSCHOOL) 
          ADM(Administrator) 
          TIMEZONE(EST) 
          DAYSAVTIME(*NO) 
          WEB(*HTTP) 
          MAIL(*SMTP) 
          CNNSRV(*NONE) 
          ADVSRV(*PARTITION *CLUSTER) 
          TEXT('Oakfarm Montesorri School - Primary')
          NETWORK(TCPIP) 
          TCPOPT(*NOENCRYPT '10.10.1.123') 
          SVRHSTNAME('OAKFARM01.OAKFARMSCHOOL.COM') 
          SBS(OAKFARM01) 
          CPYADMID(*DTADIR)

TRENDMICRO/CFGSM SERVER(OAKFARM01) 
                 SMTEMP('/usr/tmp') 
                 LICENSE('SNEF-rest has been removed')

Then I used the Domino administrator to sign the normal Scan mail 
databases by the active server id.

I opened up the smconf.nsf.  I easily configured the Mail Scan.  However, 
whenever I attempt to open any of the following:  Database Scan, Pattern 
Files, Support, I get the following message:
Server Error: The server's Domino Directory does not contain any cross 
certificates capable of authenticating you.
