Watch this video for switch port access . You will need to be in global config interface mode.

Check these :
- Check that your ip adresse is not configured as a static, if it is switch it to dynamic.
- Check that the network you are trying to connect to has a DHCP server.
- If a DHCP server exists then check it's configuration, Gateway and DNS. if you can'nt do it talk to the administrator so that he can check that.
- Check that the access point is not configured with MAC adress restriction.
- Check that the gateway is active and you have all permissions to get over internet.

Hi,
If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1.
you can do the below steps
1. Create sub interfaces on the router LAN interface
2. Provide a new ip range to the new sub interface
3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info
4. on your Labtop/PC give the IP address in the newly defined range
5. Make your switch port to be in the new VLAN

This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config

Hello,

You can do a lot with this operating system.

Some of his features are: DOMAIN Controller, Active Directory, Ftp Server, DHCP, Web Server, Terminal Server, File server etc.
Here i have some very useful links.

Here's what you need to do:

First, be sure to assign an ip address(in the proper subnet) to each VLAN.

Second, use the ip helper-address command in the context of each VLAN, the address used should be the address of the DHCP server

Third, Add a scope for each additional VLAN on the DHCP server.

The switch will route the DHCP request to the proper server based on the ip helper-address command parameter and based on the ip address of the VLAN that is passed tot he server, a DHCP address in the proper subnet is automatically configured.

Here is a sample:

ProCurve Switch 3500yl-24G-PWR# configure
ProCurve Switch 3500yl-24G-PWR(config)# vlan 33
ProCurve Switch 3500yl-24G-PWR (vlan-33)#ip address 192.168.33.254/24
ProCurve Switch 3500yl-24G-PWR (vlan-33)# ip helper-address 10.1.2.250

First of all, read this M$ article on setting up DHCP: http://support.microsoft.com/kb/139904

Secondly, check the following:
1. You have defined a valid scope and ACTIVATED it
2. You have AUTHORISED the DCHP server in Active Directory (see http://technet.microsoft.com/en-us/library/cc759688(WS.10).aspx)
3. Make sure that there are enough unused IPs in the address pool
Make sure that the DHCP server service is running - and check the EVENT LOG for errors
4. Make sure that there is no other, especially unauthorized, DHCP servers (i.e. router with DHCP enabled)

Actually the best article overall to review is http://technet.microsoft.com/en-us/library/cc781697(WS.10).aspx, which gives a big picture view regarding the role of DHCP autorization and what can happen in a mixed environment

tell each vlan about DHCP server using

ip helper <DHCP servers ip adddress>.

in config mode.

try using predefined IP addresses. Let each pc make it's own IP address and see if the conflicts continue, if they do, post again. :)
