We have a mac os server machine sharing a folder. The environment is mixed windows pc and mac. We recently installed a new server with a fresh install of Windows 2008 R2. When trying to access the Mac share from this particular Windows server the network speed is really slow, taking 30 seconds to copy a 100k jpg.
We have tested from all our other Windows servers (6) and they are all connecting and accessing the share at gigabit speeds. We have tried updating nic drivers, adding a new nic card, different ports on our switch, etc without any help.
Here is the wierd part. The slow speeds are only when you access the share by name (\\macserver), if you connect via IP address (\\192.168.1.10) it seems to run at full speed. To avoid any dns issue, I added an entry for the macserver in the Windows server host file but that did not help.
Again, this new Windows 2008 R2 machine is the only pc having this issue.
