You are most likely of Romanian origin due to your surname, which refers to a subgroup of Romanians called Muntenians, or a region of Muntenia.
You have no relation whatsoever to Vlachs from NE Serbia from what I can tell. This is something made up by some Serbs, that those Vlachs in NE Serbia are some old locals. Vlachs in NE Serbia are ethnic Romanians who migrated to that area 300 years ago.
Romanian language has linguistic ties to Albanian language, which means they were in close contact in Early Medieval times. E-BY4465 does exit in Romanians. And so do various other Albanian lineages.
Around 40-45 % of the entire Romanian population has migrated 800 years ago from the Balkans. The rest descends of Slavs, Turkics etc.
Proto-Romanians used to live in modern day Kosovo or SE Serbia.
It is no wonder that your clade exist in Vlachs considering all these ties. My clade, distant cousin to your clade is a bit more tricky, as it does exist in Romanians and around the Balkans, does not exist in Albanians. It can only be some Moesian proto-Romanian without any Albanian links or Dacian, brought to the Balkans by the Turkics who controlled Romania prior to Romanian migration. The latter is more likely atm, and soon enough I will know that 100 %.
Overall Z17107 originates in North Carpathians in LBA and EIA, most clades are found there.
You do not show any closer relation to Albanians, your distance is 1300 ybp so you fit into proto-Albanians who joined early Romanians/Vlachs during the time they lived together.
BTW I do have a close cousin in ethnic Vlachs from NE Serbia, but as with many of them, his ancestry is Transylvania just 200-250 years ago.
