This Hadith, brother, is found in Jami` at-Tirmidhi, and it's English reference is Vol. 1, Book 7, Hadith 1159, and the Arabic reference is Book 8, Hadith 1192. This is the link to it:

With regards to the authenticy of this Hadith; if you read on in Arabic, it says that this Hadith is regarded as Hadith Hasan Gharib. According to the legendary
www.wikipedia.org, this is what both, Hasan and Gharib Hadiths are.
Ḥasan, (حَسَن), linguistically means good and there exist somewhat convergent technical definitions, however, in general, it expresses the categorization of a hadith's authenticity as acceptable for use as a religious evidence, however, not established to the extent of ṣaḥīḥ.
Ibn Hajar defines a hadith that is ḥasan lithatihi, ḥasan in and of itself, with the same definition a ṣaḥīḥ hadith except that the competence of one of its narrators is less than complete, while a hadith that is ḥasan ligharihi, ḥasan due to external factors, is determined to be ḥasan due to corroborating factors, such as numerous chains of narration. He then states that it is comparable to a ṣaḥīḥ hadith in its religious authority. A ḥasan hadith may rise to the level of being ṣaḥīḥ, in spite of its own minor deficiency, due to the support of having numerous chains of narration; in this case that hadith would be ḥasan lithatihi, ḥasan in and of itself, but when coupled with other supporting chains is ṣaḥīḥ ligharihi, ṣaḥīḥ due to external factors
As for Gharib, this is what Wikipedia has to say:
A gharib, (غَرِيْب), hadith is one conveyed by only one narrator. Al-Tirmidhi's understanding of a gharib hadith, concurs to a certain extent with that of the other traditionists. According to him a hadith may be classified as gharib for one of the following three reasons:
1.Firstly, a hadith may be classified as gharib since it is narrated from one chain only. Al-Tirmidhi mentions as an example a tradition from Hammad ibn Salamah from Abu 'Usharai on the authority of his father who enquired from the Prophet whether the slaughtering of an animal is confined to the gullet and throat. The Prophet replied that stabbing the thigh will also suffice.
2.Secondly, a tradition can be classified as gharib due to an addition in the text, though it will be considered a sound tradition, if that addition is reported by a reliable reporter. The example cited by al-Tirmidhi is a tradition narrated through the chain of Malik (d. 179 A.H.) from Nafi' (d. 117 A.H.) on the authority of Ibn 'Umar (d. 73 A.H.) who stated that the Prophet declared alms-giving at the end of Ramadan obligatory upon every Muslim, male or female, whether a free person or slave from the Muslims. However, this tradition has also been narrated by Ayyub Sakhtiyani and 'Ubaid Allah ibn 'Umar, without the addition "from the Muslims", hence the above mentioned example due to the addition of "from the Muslims" in the text is classified as gharib.
3.Thirdly, a tradition may be declared gharib since it is narrated through various chains of transmitters but having within one of its chains an addition in the isnād.
In conclusion, Almighty Allah alone knows the authenticy of this Hadith, but I think brother Zulfiqarchucknorris gave you a very accurate definition of the Hadith, where he stated that women should be grateful to their husbands (this neither implies that they are the slaves of their husbands and do not have any rights over their husbands [they do in some situations and their husbands have the right over them in others, and my proof is the Glorious Qur'an] nor does it mean that their husbands should not be good and grateful to their wives too and treat them badly), and and may Almighty Allah bless him for that.
'In Sha' Allah Ta`ala you find this post beneficial and an answer to your question. Ameen.
