Hi there,
Your first switch is still int VTP mode client. You need to configure it as the vtp server:
! vtp mode server !
You should also take the opportunity to configure a VTP password too, to prevent rogue VTP servers flattening your network.
Once 'Switch' has been made a VTP server, the 'second switch' as a client should update its VTP database.
cheers,
Seb.

What is the switchport configuration between the two switches? Is it a trunk link?

Can you post the output on both switches of the command

Thank you for the output. What you gave me was output of show cdp neighbor and what I requested was output of show cdp neighbor detail.

Hello
Are these trunks or L3 interfaces?
Show interface Trunk
NOTE:
They need to be trunks, and if they are and your trunks are up and allowing all vlan tor traverse that trunk, Then I suggest you create an addtional vlan on the server to initate Vlan Memebership Anouncement (VMA) messages and test again.
switch1
conf t
vlan 500
exit <------------ this is important need to type exit for the vlan to applied

Hi
You need to enable trunk mode between switches, verify the domain, password and also check the version, you can use these commands:
trunk example:
interface g1/1/1
switchport trunk encapsulation dot1q (new switches have it implicit, so you can omit it)
switchport mode trunk
no shutdown
show interface trunks
show cdp
show vtp status <-- here you will verify the mode, domain, version and revision.
show vtp password (check if you have not left any space at the end of the password)
Everything must match
