Re: [Veritas-bu] Can Netbackup work on a DHCP network
It's perfectly fine to use DHCP for Windows servers as long as you use reservations. The good thing about using DHCP for reserved IPs is if the network configuration changes, you don't have to manually update the values on every box as it can be done through DHCP.

DHCP prevents netbackup from using reverse lookup. I have found in the NB_5.1 Admin2 Manual that a registry edit was needed on the client. On the server the dynamic client entry was added using the bpclient command. The DHCP Announce Interval for the client was enabled using the Admin Console Network Client Properties. The client is Windows 2003 and the server is Solaris 9. Both machines have NB_5.1 MP4. Server initiated backups work and the server can restore. The client cannot see it's backups with the GUI - gets a socket time out error. The client also cannot initiate a user backup. Will Netbackup work on a DHCP network?

Re: [Veritas-bu] Can Netbackup work on a DHCP network
Yes there is that, although the renewal process for DHCP should mean that this may not happen. Even so, as mentioned before, an exclusion should be in place for Servers ideally!

Re: [Veritas-bu] Can Netbackup work on a DHCP network
It's not as bad as it sounds. You just have to make sure that the DHCP server modifies DNS records (forward and reverse) for each client as it hands out DHCP leases. You should have your servers acquire static leases (where the given MAC always gets the same IP addr) so they are always in the same place. But the clients can move around as long as the DNS server gets updated so you can do forward AND reverse lookups. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ed Wilts Sent: Monday, June 12, 2006 3:05 PM To: Carl Mathews Cc: veritas-bu@mailman.eng.auburn.edu Subject: Re: [Veritas-bu] Can Netbackup work on a DHCP network On Mon, Jun 12, 2006 at 02:54:46PM -0500, Carl Mathews wrote: Our networks are changing from static IP to DHCP.
