LAN Switching/Trunking issue

I'm picking up slack while the network engineer is away on vacation, I'm new here and unfamiliar with this network.  Hosts are not getting leases from DHCP server when patched into a Cisco 2960 switch, instead they'll get the 169.254.190.178...This switch is uplinked via G0/1 to FA0/13 a Cisco 3560 switch which appears to already be configured for trunking.  Anyone care to help me troubleshoot this?

2960-G0/1:
interface GigabitEthernet0/1
 description Uplink
 switchport trunk native vlan 1001
 switchport mode dynamic desirable
 srr-queue bandwidth share 10 10 60 20
 queue-set 2
 priority-queue out
 mls qos trust cos
 auto qos voip trust

3560-FA0/13
interface FastEthernet0/13
 switchport access vlan dynamic
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 1001
 switchport mode trunk
 switchport voice vlan 151
 switchport port-security maximum 3
 switchport port-security violation restrict
 srr-queue bandwidth share 10 10 60 20
 priority-queue out
 mls qos trust cos
 auto qos voip trust

Well, definitely could be the dot1x authentication (my bet).

Is the DHCP server in the same VLAN as the PC's?  If not, double check the layer3 VLAN interface (assuming on the 3560) has the "ip helper-address <dhcp server ip>" command on it.  Also double check the DHCP scope exists and is active.

The DHCP server is on a separate "Server" VLAN, but the ip helper address is configured on that VLAN's interface.  The DHCP scope exists and is active.  Supplemental: The 3560 switch is uplinked to a Core 3750 Switch, which is where the ip helper address is configured on the server VLAN's interface...So the chain is: Host - 2960 - 3560 - 3750 - DHCP server

Is the 2960 a new addition to the network?  Can you post a "show int trunk" from the 2960.

The 2960 may be a new addition, not sure.  I believe that all company 2960 switches were recently reconfigured for dot1x authentication.

What VLAN is the PC a member of on the 2960?

guitar_daveAuthor Commented:
VLAN 205 is the corp VLAN that most users are on, my laptop is on admin VLAN 240

JFrederick29Commented:
Which VLAN are you testing with?  If you put a static IP from that subnet on your test PC, can you communicate with things?

guitar_daveAuthor Commented:
I'm testing with only my laptop at this point, which is on the ADMIN VLAN 240.  After assigning static IP info, I wasn't able to ping anything, not even the 2960 switch I was directly connected to.  One bit of behavior that I noticed when I first patched into the switch (before I set my IP to static) is that I was leased valid IP info (from my reservation) from the DHCP server for only about a second until it changed to 169.254.190.178 and knocked me off the network.

You're right.  I just located a doc from the network engineer with instructions for helpdesk to change the default gateway on all the 2960's.  They must have missed this one, I made the change and voila, works now.  Thanks a lot for your help!
