Event ID 1003 Source DHCP

Source = DHCP
Type = Warning
Description = Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address . The following error occurred:
. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."
Adrian Grigorof (Last update 9/25/2008):
If the DHCP server works properly then this generally means a network or connectivity problem. Try to isolate the physical equipment that connects the workstation in question to the DHCP server.

Reported errors:
- The semaphore timeout period has expired.
- An operation was attempted on something that is not a socket.

As per Microsoft, these events may be recorded on ISA server that is using DHCP to obtain an address for the external network card. The suggested resolution is to uUse the System Policy Editor inside the ISA 2006 Management Console to enable DHCP from External networks.

These settings apply to the ISA server as a DHCP client only. All rules
governing DHCP service TO clients should be configured via normal firewall
policy rules.

1) Open the ISA Server Management console (msisa.msc)
2) Expand the ISA server object, right-click on Firewall Policy, and select
Edit System Policy.
3) Under Network Services, select DHCP. There are two configuration tabs for
DHCP: General and From.
4) On the General tab, check Enable to allow access between trusted DHCP
servers and the ISA server. This option is enabled by default.
5) On the From tab, click the Add button.
6) Expand Networks, select External and then click the Add button.
7) Click Close and OK to finish editing System Policy rules.
8) Click Apply to save changes and update the configuration.
