Hi there
I've googled this error and found some information that may help you:
Start > Run > dcomcnfg.exe
then in the Component Service window:
Component Services > Computers > Right click on My Computer > Properties > MSDTC tab > Security Configuration ... (Button) > check 'Network DTC Access' > select 'No Authentication Required' option > OK!
see below link to know more:
