Hi,
I have sql 2005 localy , dev edition (local01) and server
with entpr. edition (server01)
opetion clr enabled = 1 (service restarted)

I create udf and try implement it

CREATE ASSEMBLY [YahooGCSQL]
AUTHORIZATION [dbo]
FROM '\\superserver\public\dba\YahooGCSQL.dll'
WITH PERMISSION_SET = EXTERNAL_ACCESS

1. on local01 it work fine
2. on server01 getting error
Msg 6501, Level 16, State 7, Line 1
CREATE ASSEMBLY failed because it could not open the physical file '\\superserver\public\dba\YahooGCSQL.dll'': 5(error not found).

I use domain acount with dba permission on local01
and server01

account is admin on local01 and has lmited access on server01
it work on server01 ,when I login server LOCALY using my domain account


what server permssions (account already DBA on sql server) account should have to run CREATE ASSEMBLY remotly ?

Add your sql server domain account to that \public\dba shared folder and give read access.

folder is really public for all domain users
