An error has occurred in the program Anybody has any idea what is the issue? i am getting this even if i run from command prompt

I am getting the same Identical error. I cannot find a resolution and may have to result to calling Microsot to fix it. Anyone have any ideas?

we resolved the issue you have to use adsiedit and modify some attributes in AD go to the ms-Exch-Resource-Schema under schema configuration then where it says display name if you see anything that says DUP with some numbers, remove the DUP and numbers and should just show the schema atrribute for example ms-Exch-Resource-Schema should show as ms-Exch-Resource-Schema not as DUP12312311ms-Exch-Resource-Schema we had to do that on 2 location which i do not remember right now

If I bring up the properties of ms-Exch-Resource-Schema the classDisplayName and DisplayName show as <Not Set>. Do you think I need to set these? I cannot find a value with DUP anywhere in the properties.

it was somewhere there if you scroll down. it might be a different situation for you. if you do not see anything there, then you better contact microsoft support

Thanks. Guess I'll have to call them

did you ever get this resolved? i have the same issue.

ADSI Edit Connect to Schema Double Click on CN=ms-Exch-Resource-Schema check all these attributes in the schema: changetype: ntdsSchemaAddadminDescription: ms-Exch-Resource-SchemaadminDisplayName: ms-Exch-Resource-SchemadefaultHidingValue: TRUEdefaultSecurityDescriptor: D : S : [there are not supposed to be spaces there, but it kept giving me a smiley]governsID: 1.2.840.113556.1.5.7000.62.50047lDAPDisplayName: msExchResourceSchemaname: ms-Exch-Resource-SchemaobjectCategory: CN=Class-Schema,<SchemaContainerDN>objectClass: classSchemaobjectClassCategory: 1rDNAttID: cnschemaIdGuid:: EdNJrXyVzUO3zdAFqGir7g==subClassOf: toppossSuperiors: containermayContain: msExchResourceLocationSchemamayContain: msExchResourcePropertySchema in my case, the mayContain attribute had a DUP entry in it. remove that DUP entry. hit ok. hit ok. allow the schema time to propigate throughout the directory. try to install again.

also had to go to ms-exch-resource-property-schema change ldapdisplayname that had a dup prefix and guid suffix to: msExchResourcePropertySchema
