It is not for certain this show exists. The date 26 July 1998 is definitely wrong, as this is a Sunday (the show only aired Mon-Fri). There are no other missing dates nearby, so it would be a typo in the month or year.
Of the two listed guests, if this is from 1998, this would be Train's first appearance (of many) on the show, in the same year their first album was released (February) and later became a hit. But their first appearance is listed on this site as being in 1999, which might make more sense as their popularity didn't really break until early 1999. So this is possibly a missing appearance from a later year.
Shaun White, if this is from 1998, was 11 years old. Though he was a "pro" by that age, according to his website his first appearance on this show was in 2010 when he was in his mid-20s. However, that is suggested to be his ONLY appearance, so this couldn't be a later show.
