Error creating an External Link

Scenerio:
While creating an External Link,



I got the following error.
Content type '0x01010007FF3E057FA8AB4AA42FCB67B453FFC100E214EEE741181F4E9F7ACC43278EE811' not found in web 'http://localhost'.

Reason:
I searched for the same word in 12 HIVE and found that its part of PublishingResources feature.

Few Options :
1. IISReset

2. Try running the following command from command line

STSADM -o activatefeature -name PublishingResources -url http://localhost

If the above command execute sucessfully , then IISReset

If you got the error "Feature 'PublishingResources' is already activated.
3. Try the force attribute like this :

STSADM -o activatefeature -name PublishingResources -url http://localhost -force

and then IISReset.
