Smile disable "Mutual Authentication Required" option

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:
