Sometimes it fixes it if you change the VTP domain on the server to
something random, then back to the real one again to restart the
advertisment. Its always been a pain on switched networks.

Subject: Strange VTP problem
Hi GS,
I'm pulling my hair as I cant figure out why VTP is not getting
synchronized between two directly connected 3550 switches. SW1 is server
and SW2 is client. I've created a few VLANs on SW1 but they are not
being propogated to
SW2 via VTP. Domain name is VTP01 and no vtp password has been
configured.
From my experience the MD5 digest of two switches must be the same if
they are to exchange VLANs. In this case however, I cant get them to be
the same even though both switches have identical vtp configuration.
The show vtp status command output for the switches is as follows:
PLEASE help guys!!!!
SW1(config)#do sh vtp sta
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 12
VTP Operating Mode : Server
VTP Domain Name : VTP01
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x15 0xD2 0x16 0x8B 0x2B 0xAB 0x98
0x4B
SW2(config)#do sh vtp sta
VTP Version : 2
Configuration Revision : 0
Maximum VLANs supported locally : 1005
Number of existing VLANs : 5
VTP Operating Mode : Client
VTP Domain Name : VTP01
VTP Pruning Mode : Disabled
VTP V2 Mode : Disabled
VTP Traps Generation : Disabled
MD5 digest : 0x9F 0x69 0x29 0xFF 0xA1 0x48 0xB4
0xAB
Thanks in advance!!!!
Regards,
Salman
