NBU备份CATALOG报错

NBU：5.1MP4,平台为WIDOWS2000

catalog备份目标指向本地磁盘，在执行backup nbc catalog时报错，status code为26，具体信息如下：

2009-12-10 13:57:32 – begin Catalog Backup

2009-12-10 14:00:31 – Error bpbackupdb(pid=2336) cannot execute /usr/openv/netbackup/bin/bpbkar bpbkar32 -IEL -nfsok -dt 0 -kl 0 -ru root -nocont -no_security C:Program罓FilesVERITASNetBackupdb on dr_media1

2009-12-10 14:00:31 – end Catalog Backup; elapsed time: 00:02:59

client/server handshaking failed(26)

2009-12-10 14:00:31 – Error bpbackupdb(pid=2336) NB database backup to path E:catalogbackup2 FAILED

请问是什么问题呀？另外NBU在备份CATALOG时还与CLIENT有通信是吗？这个通信的目的又是什么呀？
