Unable to drop connection to the Database

Hello,

I have rep server like below

A-->RP01-->RP02-->B

A-->primary ase

RP01-->primary rep server

RP02-->Replicate rep server

B-->Replicate ASE server

Now i have shutdown B and forgot delete B's information from RP02 and later build new server C in place of B

Now when i am trying to drop connection of B its not getting dropped as B is no mmore there

Any forcefull ways to remove B's information from the rep server

Thanks
