Release notes till XenServer Provisioning server 5.6

Jag hittade en grej i release notes till Provisioning server 5.6 som jag inte tror att alla vet om

Releasnotes hittar man här:

På sidan 12  (av 15) står det:
TR-8435: Occasionally server stops responding to booting target device requests for 2-3 minutes.

The default lifespan of ARP cache entries was lowered from 10min in Windows Server 2003 to a random value between 15 and 45sec in Vista/W2K8. As a result, the PVS bootstraps are twenty times more likely to experience a timeout during a Vista/W2K8 boot. The workaround is to increase the ARP cache entry lifespan for PVS-bound NIC‟s:

1 Open a command shell window. At the command prompt, enter the following command:

netsh interface ipv4 show interfaces

2. To set the ARP cache entry lifespan to 600 seconds, enter the following command:

netsh interface ipv4 set interface basereachable=600000

3. To verify the new setting, enter the following command:

netsh interface ipv4 show interface

The “Base Reachable Time” should be set to 600,000 ms, and the “Reachable Time” – to a value between 300,000 and 900,000 ms.
