We have a Windows Media server that has both a 1Gb and a 10Gb connection (only 
1 however is enabled at a time).
When running on the 1Gbe interface the backup speeds are normal.  All clients 
backup at speeds from 40 - 80 MB/sec.
When however disabling the 1Gbe and enabling the 10Gbe interface (same IP 
settings) all Solaris clients backup at speeds of 40-50 KB/sec, while Windows 
and HP_UX clients still backup at the previous mentioned speed (40-80 MB/sec).

Has anybody any idea ?  The 1Gbe interface goes to a different switch then the 
10Gbe fiber cable.
